Mount Bross

This was a pretty easy trail to drive. Any vehicle with decent clearance should be able to do this. Maybe some lose rocks and a few potholes/ruts would be the biggest concern for low clearance vehicles. I never needed to use 4wd. The views are beautiful! This is a great beginner trail to mosey along at a slow pace and take in the views and maybe even stop for a picnic.

If you follow the path that Trails OffRoad has laid out it’s a fun trail for stock SUVs & pickups. However, it’s easy to drive past waypoint 10 and not even realize there was a fork there and soon you’re on your way up the summit road. It would be nice if someone would put up a sign, gate, fence... something at waypoint 10 to discourage people from making the wrong turn and end up regretting their decision. Trust me.

Fantastic trail. The scenery and bristle cone pines are amazing. Drove to weather station and turned around.

We've been up Mt. Bross several times, but as of Aug 2021, there was a new, very bad off-camber spot as we ascended after waypoint 9 and well before waypoint 10. A runoff/drainage spot has developed crossing a few upper switchbacks, and we were the closest we've ever been to flipping our Jeep- and it's a LONG way straight down from that spot! For a fairly easy trail, I would recommend skipping the northern part of this 'loop', and we hope TrailsOffRoad can go back soon to add another waypoint specifically for this spot. By the way, the view from the top looking from the Collegiate Range over to the Mosquito Range and down toward Mt Lincoln & Alma is amazing!

Reports of snow at high elevations and folks going off trail to avoid drifts. While this trail may be passable by experienced groups in very capable rigs, we feel it safer to designate the trails as *IMPASSABLE* at this point.

Finally some clear skies!! So great to get up high! (But, MAN it sucks to have to skip the summit road.)

Fun trail! I ran it in my 07 Subaru Forester (6" total of lift) and had no problems at all! I skipped out on the summit road because I had heard that it was all private property and closed off, even for hiking Mt. Bross is closed, so I just stuck to the loop. Loved seeing all the old mines and the information TrailsOffroad gives about them!

We took the trail was very nice drive but we came to find out after that it’s on private property and you’re not supposed to go to the top.

Calvary 4-Wheelers ran Mount Bross as part of our annual Aspen Viewing trip on Saturday, September 26, 2020. We had seven rigs along for the run, a stock TJ, a stock JK, a moderately lifted TJ, a well-built JK, two built XJs and a stock Ford Ranger. We ran Buckskin Joe in the morning as the first half of our excursion and start this trail early in the afternoon. There were not a lot of aspen along this trail but it was a very fun trail just the same. The lower part is indicated on the maps as suitable for passenger cars but is a little rougher than a typical graded gravel road. It did not require 4wd but you would have to be very careful without high clearance. Once we got past Waypoint 4 and started the loop 4wd became necessary. The trail was rough enough to be fun but not so rough as to be a major challenge, even to the stock rigs in our group. All of those stock rigs made it through the ruts at Waypoint 9 without assistance, although one did lift a tire about a foot off the ground. Fortunately she had just enough momentum to have all the tires back on the ground before loosing traction. As noted in an earlier trip report, the spur to the saddle did have some snow left from the early September storm. It had melted enough that we only had to cross the edge of a few drifts and were able to make it to the top. The next significant storm will probably make this section immpassible until next summer. There has been some discussion about a possible attempt on the summit, but it was getting later in the afternoon by the time we got to the saddle and it was cold and windy so we scrapped those plans. From the looks of it, though it would be pretty easy to bag both Mount Bross and Mount Lincoln from there if you had an earlier start and favorable weather.

Ran this trail on 9/19. I was able to complete the main loop portion, plus the spectacular overlook on FR 285. I was only able to make it to about waypoint 13 on the road to the summit of Mount Bross before I found the shelf road increasingly blocked by snow banks leftover from the storm two weeks ago, and had to turn around. That snow could melt out still this year, but my guess is it that upper portion of the trail will likely be impassible until next year. Beautiful scenery and I hope to try again to reach the top next summer, hopefully with less smoke in the air spoiling the views.

A pretty easy trail in a stock UTV. Great views! The hardest part was going down slow.

Went all the way up and hiked to the peak of Mt. Boss. It was a god day. It is not a difficult trail just a few areas were you feel tippy on the shelf road areas. Going with the way points after the wash out area going up it was lose rocks.

Wonderful trip. All clear of snow and no traffic.

Awesome trail! Nothing too challenging, deep ruts were fun - the washouts were white knuckle but you'll get through them fine, take em slow! Hiked up the last ~500 elevation to the summit of Mt Bross and the views of Kite Lake and the other 14ers in the area were amazing!!!! Saw about 6 marmots at WP 3.

Easy trail all the way up with lots of side roads to explore and mining locations to explore. Stay to the East side, avoiding the loop that begins at waypoint 18 and ends at 24 as there are snow drifts blocking the way. A very large snow drift is just past waypoint 18. There is a smaller one I was able to get past higher up the mountain and rejoin the trail as marked here at waypoint 12, but getting past the snow drift was a bit sketchy and I'd not recommend it.

What a thrill ride! The highest trail in the state! It snowed on us near the top. Snow! In August!! How cool is that?
