Leavenworth Creek Road (AKA McClellan Mountain)

These trails are at a high altitude and are impassable until next season!

The season's first real snowstorm has moved through the Colorado High Country, and the daytime temps are not low enough to melt the storms anymore. This trail should be considered only partially open at it's lower altitudes and may be dangerous if you encounter snow, if not impassable, until Spring.

Great relief to leave the crowds behind on Guanella! We only ran this to way point 10. It was late in the day, and we were tired but really enjoyed the trail. The first quarter mile or so is definitely the gate keeper! We came across a Lexus SUV backing down it when we arrived, and another SUV and small truck backing down it when we came back. There were plenty of Aspens to keep it interesting and one of the first campsites has a great location next to the creek. Our favorite part was actually the final designated campsite - way point 9- someone fashioned a table and bench at the lowest point and if you walk out through the brush you are rewarded with an amazing view. Hope to return next year and complete it.

Ran this one today along with Argentine. Made for a long day, but wow! What great scenery! There are not a lot of pullouts near the top, so timing is a key. Thanks to the young man in the white Cherokee that backed up about a quarter mile to let our group through. He did well, and it was very much appreciated...

This trail is always a lot of fun. The hardest part is right at the beginning with a few step spots and some rocks to navigate through but it's not awful and I've done it in my jeep and my subaru without issues. The trail was a little wet because it had rained but not much and I think it just made the trail better to drive. One or two puddles and if you're going to the Santiago Mill, the last half mile or so of the trail is steep and loose with 2 spots that will need a little proper wheel placement. Go have fun.

Open to the top. Visited this road for the first time with friends from Colorado Land Cruisers (Colorado Springs). It is a narrow shelf road with some switchbacks but nothing too great for a stock 4x4. The views are 5-Star!

Super fun trail, there weren’t any obstacles. It gets off camber though and it feels tippy. Also towards the top there are hardly to no areas to pass, but it’s pretty easy to spot approaching vehicles. This trail isn’t super steep since it used to be a railroad grade, it’s just all shelf road.

Users have reported it's clear to the top,

Great condition! Water crossings were great. This trail should be a green in my opinion. The trees are tight but you can make it without scratches in a Jeep. Rain would make it a yellow but normal conditions it should be green.

Users have reported it's clear to the top, but it isn't 100% clear if that includes Denarious Mine Road, that wraps around the mountain and comes back. Use caution if you encounter snow at high altitudes.

I ride a bike, but there was no snow from waypoints 9-18. can't speak about the condition of the trail for waypoints 2 through 9 as I take argentine pass at the beginning of my trip.

Trail was washed out at Waypoint 4 forcing larger vehicles into a tree trying to traverse the muddy bank. Additionally trail is impassable halfway between waypoint 15 and 16 due to lingering snow at high altitudes. Otherwise was an incredible trail with a ton of fun obstacles and beautiful mountain vistas.

We went up the lower part as far as Waldorf just to drive the crossing. The creek is rushing but only a few inches above normal.

Made it a between waypoint 15 and 16 today before encountering deep snow. It will probably be a couple more weeks before it opens all the way up. The water today was pretty deep, it swallowed my 35’s and was working up my door about six inches in my JKU. I would recommend bypassing these sections by using Argentine if you’re in a lower vehicle.

Tree down on the trail as you climb up the rock / river toad at obstacle 4. Cannot pass tree, road is extremely washed out and had loads of water running down it.

I don't have much to add to trail conditions as I only went to Waypoint 4. But I did see designated campsite signage (specifically saw sites 6, 7, and 8) but nothing that indicates that camping was only allowed in designated spots. There were more spots early (within 1 mile) than listed here. I am curious if this has become a designated site only area or perhaps the signs I saw were for future purposes?

Made up to waypoint 7 today before encountering bigger snow drifts. Lots of water flow right now which made added some more fun to the water portions.

This trail travels above the timberline and is considered impassable due to snow until spring. See you next season!

Closed for the season! See you next year!

I only ran this from WP 15 down to 9 as part of our Argentine Pass day after checking out Santiago Mine. I agree with others here. That section was very tight and added pinstripes to my 4Runner. Coming down to WP 9 there is a huge rock right in the middle. We managed to barely make it down but a a large vehicle may not like this section section. This is one of the few times I really appreciated and needed my rock sliders.

I ran a group on the lower roads of McClellen along with going to Santiago Mine. This trail never disappoints and has my favorite close-to-home water crossings in Colorado. No changes to report at this time.

This trail is VERY tight in spots. But worth it! Loved driving the creek bed. Skipped the mine and went right for the summit. We ended up taking argentine pass back as it is a much better graded road with less rocks and faster. The views are phenomenal on clear days!

Waypoints 9-10 are very intimate with the trees and will give pinstripes. Either bring some hedge trimmers and go to town or prepare to hear those scratches. I skipped the detour out to the old mine and went straight to the summit. Turning around on the summit is pretty sketch. Very limited space to do so and if anyone else is up there it will be a nasty mess. This is not a good trail for groups. The last 2 switchbacks near the summit are off camber and tight. Definitely a little pucker factor there. This trail will suck if you need to pass anyone, so look ahead for other traffic. Passing spots are limited for long stretches of shelf road!

Snow drifts are reported to be gone or almost gone. Proceed carefully and enjoy for the summer!

Went to the mine and the ghost town but not all the way up. I’d recommend taking the road for Argentine pass to move faster. This route can be a tad gnarly up what is like a creek bed. Pinstripes too. Not that bad since I’m on 37s but it would be a lot for other folks.

I ran it to the snow at 12,300 feet there is a Gully filled with deep wind loaded winter snow after waypoint 15.

I ran this trail on June 12 and found it snow blocked between waypoints 15 and 16. The 248.2H spur just above it was clear to the end and was the highest point I was able to make it to in the area. The spur to the Santiago Mill was also open and clear to the new parking area at the mill. The creek is higher right now for spring runoff but was still easily passable.

I have received a good report that the trail is open to Waldorf mine. A few spots of ice and snow exist along the road but are easily passable. The areas past the mines and above the treeline are still snowed in.

I was in in the area, so I gave it a shot. I did t get too far before turning around. Still too much snow for my taste.

Snow has been sticking, and users report impassable icy conditions in multiple places. This trail should be considered impassable until Spring. If you choose to wheel in the snow, please do so with the right equipment and do not go alone.

Based on reports, it appears the summits for these trails are going to be impassable for the season. Georgetown and the surrounding area is getting more snow, and wheelers have already been turned back by snowdrifts. The rest of the trail is still accessible at this time.

Always a scenic trail full of fun off-shoots. We made it to the last switchback, which had about 1-2 of snow drift covering the trail. Doable on something that has at least 37s but my 33s would have had me plowing through. Still one of my favorites to do this time of year with light snow covering the trails.

Really bumpy but beautiful at the top. We (wife, dog and I) ran this trail at about noon, weather was clear and it was beautiful at the top. It’s a lot of loose rock, slow going and bumpy all the way to the top. We have a stock 21 Rubicon, no challenge at all. Going on a weekday there was almost no traffic. Saw a couple Other vehicles. One was a stock Compass trail hawk.

Ran McClellan with 11 rigs today! Excellent trail for a number of the first timers with clear views (and surprisingly no wind) at the top!

This was an exceptional trail! Ran it in a stock '17 4Runner ORP. No issues! Will definitely be coming back! :)

I ran Mt. McClellan yesterday reaching the top at 4:00 pm. It was a rain sleet mix up there and some wind about 10 mph. I ran the lower Argentine trail first then to the top. Great energy up there yesterday people were very friendly on the trail.

I love this trail. I love everything about it. We went out the weekend the forecast was looking ominous and were not disappointed. We had the entire place to ourselves camping off McClellan. We ran this trail all the way to the last 2 waypoints. The snowdrift image is heading out to the mine at WP 17. Talking to a few others running the trail, the section up to WP 18 also has a big drift. It will be a few weeks until this trail is 100%, but it's all clear to WP 16. A stock vehicle will be challenged on this trail, but it's one of the best in this area, especially this time of year. The columbines were out and it was a sight to behold.

There is still snow at the higher altitudes preventing access to Argentine Pass and the Santiago Mine. The run was fun, the spring water runoff levels were fun as well. The fording was not too deep. We were unable to make it to Santiago Mine due to snow on the trail. The amount of spring runoff made the lower trail fun and virtually dust free.

These trails are open for the season, however snow is likely still blocking parts of the trail above 10000ft. Travel to Waldorf Mine and almost Santiago has been confirmed.

WARNING! There have been multiple recoveries along Leavenworth Creek Road (The lower portion of Argentine and MCcellen Mountain) due to snow and large patches of ice. This trail should be considered impassable until the melt!

This trail is located at a higher alitude of Colorado and at this time of year should be considered impassable for any regular off-road user. Some people may be able to manage these trails with the correct gear, emergency equipment, and rig. Travel with caution.

Special note: Guanella Pass has closed early for the season due to the wildfire situation in Colorado. This trail's status is not impacted by this closure, only access to these trails is now limited. Geneva from the south and Argentine/McCllelen from the north.

FORT COLLINS, Colo. (Oct. 20, 2020) – Due to unprecedented and historic fire conditions, the USDA Forest Service’s Arapaho and Roosevelt National Forests is announcing a temporary closure of all National Forest land in Clear Creek, Jefferson, Gilpin, Boulder, and Larimer counties, effective at midnight tonight (closure begins at 00:01 Oct. 21). This decision will be re-evaluated daily as conditions change.

Multiple reports confirm that there is enough snow to make the summits impassable. The trail is reported open to the Waldorf.

Streams are running and pretty passable right now. Lots of wind on the hill today. this is a little more bumpy than Argentine but still a lot of fun. The climb out of the river is very doable and based on group comments not as difficult as previous trips.

Drove up there yesterday to get images of the new fencing at Waldorf Mine. The remediation work continues at that site and those areas have been blocked off while leaving some parking areas for people. Made it all the way up to the summit and boy was it windy up there towards the end of the day. I did not make it to the end of this trail since the shelf road had just enough snow on it to make me not want to risk the off-camber. Some folks on short ATV's made it over the snow, but they said that they wouldn't have wanted to do it in a larger vehicle.

I only did the trail in to the mine that is currently being remediated (lots of construction fences and vehicles at the mine), then part of the trail up to McClellan Mountain. I ran the trail in a stock 4Runner SR5 with full pressure street tires. Nothing I did was too technical or challenging (it seems going to Argentine is harder than going to McClellan). I'm pretty sure I could have made the summit of McClellan but I just ran out of time. As others have said, the hardest part is the first mile or so after the turn off from Guanella Pass Rd. It's rocky so you need decent clearance and careful tire placement here and there, but overall not too challenging. I saw a few camp sites along the way, but there weren't that many so I'd recommend having a back up plan if you're looking to camp here.

Got up there pretty early using a mix of the FS 248.1 (Leavenworth Creek Road/"Argentine Pass" route on Trails Offroad) and FS 248.1B ("McClellan Mountain" route on Trail Offroad). Be advised that 248.1B is very bumpy and overgrown, so there are limited passing spots and a lot of pin stripes. The smoke up there from the fires out in western Colorado was pretty thick. Road is really dry and dusty right now. Not to crowded - explored a few more of the off-shoots around the Waldorf mine site - also bumpy and narrow. Still always a good route and great views of Grays and Torreys Peaks to the West from the top of McClellan Mountain.

This one will be forever engrained in my memory. I should have posted this last year, but after that traumatic experience, it was the last thing I was thinking about. My parents were in town to visit and I wanted to give them something to remember. Pretty sure I accomplished that. We were on our way to way point 17 and encountered a decent amount of snow here (39.671433,-105.777628), so my wife got out with a radio to "spot" me across. Well, turns out that was not a good idea. We tried to "shoot" across the 10+ feet of foot deep snow and actually lived to regret it. With me driving and my parents in the backseat, my wife was on the radio setting us up to cross and my dad was egging me on. As we started across, the road gave way below us due to all of the melting snow, so I punched it and was able to work my way back up the slope to the road without rolling, surprisingly, as I was yelling for my wife to get out of the way. Once across, we all were happy until I had to break the bad news that we had to go back across. I'd like to add that my dad is a lung transplant patient that needs anti rejection meds twice a day to survive. We spent the next several hours removing snow and working on the road. This was a task without proper equipment (we have it now). I decided to go back across alone around sunset and then drove home. We got lucky, this time.

We did this trail in one day, it was a great trail. We did not see any construction at the waldorf mine so there were not any trucks on the trail. We will be going back up as there are lots of other trails to explore.

This is the best most challenging way to get to the Argentine Pass basin and to the top of McClellan. It's a rocky start so I recommend airing down to at least 12-14 psi. The trail runs alongside a river with a plethora of camping spots. When it's all done you will end up where the main Argentine Pass area is. The mountain is up to the right and the pass is up to the left. There are so many abandoned mines in the area, which makes it a great day for adventures.

Remediation work will continue this year at Waldorf Mine. Be aware that there may be construction traffic, especially on weekdays. https://www.fs.usda.gov/detail/arp/news-events/?cid=FSEPRD768377 Construction delays anticipated on road to Waldorf in preparation for mine reclamation project GEORGETOWN, Colo. (JULY 20, 2020) – Construction delays are anticipated on the road to Waldorf, Forest Service Road 248.1, from its junction with Guanella Pass Road (County Road 381) beginning at daybreak on July 24 through July 30, 2020, while crews walk in large construction equipment for a mine reclamation project. The equipment is large and slow moving and will require the entire width of the road, which is why we anticipate delays for the majority of each day. It will be difficult for motorized vehicles to pass the equipment, which has a 6 mile trip along the road to the project area. The excavator, loader, skid steer and tracked dump trucks are needed for a mine reclamation project that will address elevated levels of metals in tailings piles near the Waldorf Mine site. These tailings piles are actively impacting Leavenworth Creek, which is an important municipal water supply for Georgetown. The USDA Forest Service’s Abandoned Mine Lands Program and Trout Unlimited are partnering to address these hazardous tailings from entering the stream channel. This project is being completed through the Comprehensive Environmental Response Compensation and Liability Act (CERCLA). The road will be open while the project is underway. Work will last through the end of August 2020, weather dependent, and then traffic delays will be anticipated again while the equipment is walked out of the area.

Awesome trip up McClellan Mountain before we ran Argentine Pass. Trail is completely clear. The switchbacks at the top are tight so use caution in a pickup or longer wheelbase rig.

This trail was awesome. We went on the stretch that went up to the mine. The old mine was a really cool step back in time and the marmots of the area gave a warm welcome. If camping in the campsites along the trail make sure to practice leave no trace and wilderness safety, we got visited by an adolescent and full grown moose seperately, so you might want to be careful in mating season. There was a good bit of trash that our predecessors felt they could leave in the fire pit of our site which was the only dissapointment. Switch backs leading up to McClellan were narrow without much room for passing, but an easy enough trail for beginners whith the right setup who want some awesome views.

I absolutely love the trails in this area. We ran up Argentine and then came down Mclellen today. Unfortunately there is still a snow drift blocking the last leg to get to the top of Argentine Pass, but don't let this stop you from exploring these traiIs. I recommend checking out the Santiago Mine while you are up there. Without a doubt, Mclellen is my favorite since there are several water crossings and a small section of the trail is in the creek.

First time up here - what an absolute blast of a trail! I much prefer this to get up to the Waldorf area than Argentine. Such fun water crossings! This trail had awesome camping opportunities also. As always, stay the trail and clean up any trash you see. This trail was not open to the summit - not even close.

Did a combo run of McClellan and Argentine, taking McClellan through waypoint 9 as described above. More ice in the shade than we were expecting but doable in a capable vehicle. Both water crossings had ice dams forming, they were surprisingly deep and the ascent out of one was icy as well. Not too much effort needed with moderately modified vehicles but I did need a strap on one uphill with ice. I wouldn't recommend tackling it solo unless you have the right vehicle and experience, the next decent snowsotrm will probably close the upper portions of the trail for the season.

Trail writeup has been updated with new 2019 information. Waypoint 12 had the biggest change with the closure of 248.2B.

None of the summits are open, I got stopped at about 12,000 before hitting impassable snow. There's another visible snowbank up the trial a bit as well Trail updates with the closures and more to come in the next few days.

Trailsoffroad spoke to Trout Unlimited to get additional details on the remediation work going on at Waldorf and was able to get additional details on the changes on the trail.

First and foremost, these trails will largely stay open. The FS is required by law to keep these trails open for a variety of reasons. The network of trails is vast in the area though and they appear to be moving things around to manage the area better.

There will be no major remediation work at the mine this year. Crews will be working to do some vegetation and prep and stabilization work for the Waldorf mine area for 2020. Access to Waldorf mine is TRESPASSING and you will receive a ticket if caught.

Late last year, the Forest Service decommissioned the spur known as the "Hill Climb" at Waldorf. We have not spoken with the FS yet, but it's believed that this wasn't part of the original network of trails and the FS may have closed it to discourage further inappropriate use of the Waldorf site.

We will provide additional updates and details as we get them.

Remediation work continues this summer on the mines in the area of Argentine Pass. I have been notified of the closure of Waldorf Mine to traffic, the hill climb at Waldorf and a side trail that leads to an old cabin. These trails are either illegal additions, or they have closed it due to major toxin issues with runoff into the Colorado water supply. Trailsoffroad is in touch with the FS and the company doing the work for them. Any updates to this project will be posted here as the information is made available. Trailsoffroad crew will be up there in the next 14 days to get some new pictures and in-person information.

Trail was open to just past the switchback on waypoint 15. Path is blocked by a large snow drift, looks like it might need a couple/few more weeks to melt. Trail was pretty fun and overall pretty easy for my mostly stock Xterra pro-4x. Water crossings were fun, but the large water crossing was about 30" at the deepest and the current was quite quick with some loose large rocks on the bottom.

Guanella Pass is open and we stopped by to see how far we could get. We got a little over a mile in before the snow got too deep for me and I was spinning tires, with my lockers on.

My annual trip up to the top of Mclellan was just as great as always. I truly love the views and solitude on this trail. Nothing new to report for the trail condition, everything appears the same as last year.

Went up McClellan Mountain trail on Sunday the 1st and had no problems reaching the top, all routes were open and water at crossings was passable. Came back down Argentine Pass at the intersection of 248.1A and 248.1K, road was dry and dusty, recommend taking lower road if going in a mildly built rig or better than stock, lower road was very rocky and fits into the "moderate" trail rating. Thanks again for all of the posts, looking forward to getting out over the 4th!

From Reader Nathan Voorhis: So just wanted to shed some light on current conditions as of today. Argentine pass is a no go just after the Waldorf mine site by snow drifts on the trail. If you try to go up the steep hill from the Waldorf mine towards the Santiago mine there are a couple impassable snow drifts. Also Mt McClellan trail has a snow drift on it past the Santiago mine

There has been a lot of snow above the timberline and much of this trail is impassable at this time. Lower parts of it will remain open for a few weeks but will soon be snow covered until spring.

We took a trip up Argentine, McCellen and Upper Geneva for a final season trip report. Coming down from Waldorf, we took this trail to see how much snow had accumulated. Please note, we stopped at Waldorf Mine. We could see snow on the trail about 1000' up and did not want to risk anything. Colorado 4x4 Rescue & Recovery is not doing recoveries above the treeline until spring. It is too dangerous. Do not travel up and risk your life and others. The lower part of the trail is icy in the shaded spots and will be rough in a snow or two. It was fun to go through here though and the creek ice was broken through (it appears one or two vehicles have been through here since the last snow) was about 2 inches thick. This trail is on the brink of a virtual seasonal closure.

We did the lower creek portion of the trail to see the foliage and get away from the crowds. The stream was low and easy to cross.

It was a great day on the trail until the storm rolled in. I had just passed the shelf road and the thunder and lightning started so we headed back below the treeline. I popped a tire's sidewall on the way down, these rocks keep getting sharper.

I wanted to find a location to witness the Great Solar Eclipse of 2017 and the Argentine Pass area is one my favorite for any lunar or celestial events. McClellan is not one of my favorite trails in terms of driving, it has long shelf roads with no passing and there is little room at the summit for parking and hanging out if others are up there. It does, however, have great scenery! We took our chances that the trail would be lightly traveled on a Monday and that we wouldn't have to deal with any impossible passing situations on the shelf road. The view from the top is amazing with Grays and Torreys Peak provided a dramatic backdrop for the eclipse.

We did the lower portion of the trail and the road was fine. The creek is much lower, but the rutting caused by it may cause us to increase the difficulty. More to come and this trail will contain new information on Monday. If taking the creek route, use caution while we determine difficulty updates.

We didn't have time to wrap the mountain and go to waypoint 17, and the status of that part of the trail is unknown you can reach the summit at the end of the trail by just climbing to the last waypoint. The creek is very high and the water came up past the bottom seam of the doors of my JK. The first crossing has a large rut forming (pictured) and we will be keeping an eye on it as the creek dries. It may leave some challenging damage.

Checking in on trail conditions. We didn't make it far down the trail. Only to between Waypoint 2 and 3. The snow is rather deep and slick.
