Highlights

Highlight: Coney Flats (Coney Creek)
This 4.8-mile off-roading trail near Boulder, CO is popular for locals and tourists alike. Coney Flats is anything but flat all the way through and offers some rough rock obstacles to start and a day driving over mainly rocks. The trail is famous in the area for the large water crossing at Waypoint 4 and the views of the Indian Peaks Wilderness. This naturally dammed creek crossing stays deep all year long and since water crossings are hard to come by in Colorado, people seek this one out. This is a 4x4 trail for those looking to test out their skills and for a full day of rough wheeling.

Ran this in conjunction with Middle St Vrain in my mostly stock FJ100. It pushed the limits of my rig and the accompanying Wrangler Sport. As soon as we departed St Vrain the initial uphill climb seemed to increase slightly in difficulty from the previous trail. At the foot of the Rock Obstacle, easily the most technical section of this trail, we began to wonder if we bit off more than we could chew. With a bit of expert direction from a seasoned driver, and some perseverence, we muddled through and were rewarded with the glorious water crossing. Yeah, we all did it at least 3 times. The difficulty and the water crossing made this a really special day, if not a gruelling one. We spent a good 6 hours off-roading alone. But it was rewarding and adventuresome. At times the wood was so thick I half expected Red Riding Hood to come skipping by. There was rock, mud, water, climbs, descents a turtled 4 runner to rescue . . . pretty much something for everyone. I slept well that night and was glad to have made it. I definitely recommend a little lift and bigger tires before tackling this one.

I completed St Vrain and Coney flats in a stock 4Runner SR5, I’ve said it before and I’ll say it again, ATRAC works wonders, the T4R didn’t even hesitate to climb any of the obstacles. I would have been a lot better off if I had a lift, I did scrape a number of times but with the help of a good spotter, I faired pretty well. It helps that the T4R has a shorter wheelbase than Tacos and 4-Door Wranglers. I enjoyed the double takes I got for being in a stock 4Runner on the trail. I’d say that the water crossing is about 18” deep based on how high the water was on people’s wheels. This is a long drive that can cause you to be fatigued toward the end, be ready to pay attention to the trail, a lot!

Ran both MSV and Coney Flats in our JLUR with 3" lift/35s and had a blast...one of the most fun and wettest trails we've ever done, and the views from Coney Flats around the main water crossing are breathtaking (as you'll see in the photos). Agree with the 5-5 (for MSV) and 6-6 (for Coney Flats) ratings....you'll be tired after this trail because it's near continual effort...but FUN effort! Took us about 4 hours (with brief lunch stop at CF's main water crossing. You'll get lots of water (many muddy) crossings depending on recent rains. One of them along MSV toward the western end was several inches deeper than the main CF crossing (which was ~ 2 ft). Overall, this combo of MSV and CF is now one of our favorites -- great shape, great fun, and absolutely beautiful!!

The Mountaineers, a 4x4 club from Fort Collins, embarked on a late fall season trip to Coney Flats and Middle St. Vrain. With winter weather setting in soon, there are not many more weekend opportunities for these twin trails. There was still considerable water present on the trail, however, despite the near 50 degree conditions, icy conditions seem to have moved in for the season. The aspen trees donning the trail are all past their peak color and most have lost their autumn golden glory. The local District Forest Ranger will close this trail for the season once inclement weather overtakes the foothills for the season.

A stormy day on the trail. It rained on and off as we came off of here. We took Coney Flats to MSV and then out to 72. There was a lot of foot and vehicle traffic all day.

A group of us from trailsoffroad.com ran the Middle St. Vrain and Coney Flats off-road trails for a meet and greet event. We had four rigs which consisted of two Jeep Wrangler JK, a Jeep Cherokee XJ and a Toyota Tacoma 1st Gen. Coney Flats and Middle St. Vrain are Jim Dixon's trails to prepare the guide for, so the rest of us, Lauren Martin, Brad Martin, Scott Bram, and Myself all we had to do was have fun. Fun is what we had on this trail combination that offers forest scenery, mountain peaks, and, of course, some light rock crawling! Being so close to Denver and Boulder, Colorado, these trails are a must do for anyone and I run them at least a couple times a year. In addition to running the trail together to get to know one another, some of us had other motives. Lauren had just purchased the new DJI Phantom 3 Professional drone and wanted to experiment with it on this trip. The plan was to capture the vehicles crossing the major water crossing on top of Coney Flats with the Indian Peaks in the background using the drone. I ran this trail back in July as well, it seemed more dry than normal, and this time proved even drier. Even though the water wasn't as deep, it was a perfect location to set a drone up and film away! With almost no crowd, the day proved to be a very pleasant and relaxed on the trail. I always forget that there is a perfect lunch spot at the lake, and I really should have brought some food to grill or barbecue. There is enough space to park at least 15 vehicles at the lake, so if you are with a group, this is the place to stop. All the obstacles were dry and easily conquered, where sometimes they can be a bit slippery and tougher to do. Next trip back to these two trails I would like to camp along the St. Vrain Creek.

This was the first official run with a group of contributors from TrailsOffroad.com! It was a great time finally meeting some local faces. Our group consisted of two Jeep Wranglers, a Jeep Cherokee, and Toyota Tacoma. We couldn't have asked for a more beautiful day to run the trail and we even got to enjoy seeing the colors of the trees changing for fall. We started our run on the connecting trail Middle St. Vrain. The trail did have a bit of traffic once we reached the first big obstacle on that trail, but we got through it easily and let the larger groups pass by ours. We finished up pretty quickly on Mount St. Vrain and continued onward to Coney Flats. The group maintained a good speed on the trail without much issue. Some of the obstacles had a little residual water and mud left around them which proved to be challenging for the more stock vehicles. Once we reached the Lake Crossing, we stopped for some lunch, and I pulled out my new DJI Phantom 3 Professional drone to get some cool shots of the area. Once finished we cruised out the remaining section of the trail at a good pace. It was a good day!

Great trail that connects to MSV it's a little more challenging but just as beautiful.

Questions & Answers (4)

Q: Hi J&J, I'm fairly familiar with this trail from mountain biking, but I also know very well that things behind the wheel can be quite different than from behind the bars. I'm a beginner and am not ready for the rock garden, but my recollection is that from Beaver Res. to the flats is not nearly as technical. (When the gate opens) what would you give the rating of that eastern section? Thanks!

Q: The info section lists the best direction to travel as West, every time I've ran Coney we came from MSV and traveled East, is that not the standard route?

Mapping Crew - Colorado

Jen & JD moved to Colorado from Chicago in May of 2015 for work and brought with them a 2001 stock Jeep Wrangler that had been garage bound for two years. Within a month of arrival, all rusty 170,000 miles of it was shaking on Colorado trails and they've never stopped. As time as gone on, their 2001 TJ has been upgraded and a 2015 Jeep JK has been added to the family. JD works as a Systems Engineer for a cable company and Jen runs a business from their home during the week to pay the bills. When the weekend hits, they're almost always hitting the trail. When Sunday night rolls around, the question turns to, 'so what's next week?!'.
