Trail Information


Sugarloaf Mountain is an easy scenic dirt off-road trail that takes about an hour to complete. It’s located in the foothills just west of Boulder, CO and is accessible year around. The drive gradually winds through aspen and pines forests with some nice views of the area valleys and gulches. The hills are bursting with gold color when the aspen trees transform in the fall. This section of Roosevelt National forest is full of old mining sites. Hiking, horseback riding, and mountain biking are common activities around Sugarloaf Mountain. It is not unusual for these other activities to take place on the road, so drive with caution and share the road.

This Sugarloaf mountain trail is nothing like the description or the video. It was more than 2 hours of the most tedious driving I have ever done. This is a road of nothing but rocks, 5 mph or less all the way. Maybe the description and video are old or maybe I spent the day in an alternate universe. Trailsoffroad should take another look at this trail. The locals tell me that the Switzerland trail road just to the north is much more difficult.

Flat, dry road. I would mark it as a 1 on TO's scale.

Fullsize Truck Review - First time on the trail and it was a bit rockier and washed out than I thought it was going to be. People made it sounds like a casual back road. However, it is nothing. I didn't air down, which probably would have helped. Totally doable in a full-size truck as I never felt too big. I did rub a couple of branches but could have avoided them if I was paying better attention. Ran into a couple of folks and we had to pass and it wasn't an issue. There are a few spots where it would be impossible to pass and someone would have to back up. So pay attention and make note of spots as you go by them. Overall, a fun trail with great views and nothing any stock 4x4 couldn't handle.

Deep snow pack made for a fun time when we ran this trail until about a little under a mile after waypoint 4 headed to 5, when the small ATV that was the first to run this trail that day was stuck in about 2ft of snow. He was getting pulled out when we got to him and after that we all decided to head back to the trailhead, but there was others still going to try after we passed them and warned them.

Nice easy route to do as our first time off-roading in Colorado in our 2020 stock tacoma trd offroad. Was kind of busy, but trail is mainly wide and easy to stop and pull over as necessary. Lots of gravel bikers. As mentioned in the previous post, there is some washed out parts, but nothing the truck couldn't handle.
