Trail Information

Highlights

Sugarloaf Mountain, one of the closest offroad trails to Boulder, offers stunning views of the snowcapped Rockies to the west. The drive gradually winds through aspen and lodgepole pine forests with lovely views of the area's valleys and gulches. The hills burst with gold color when the aspen trees transform in the Fall. This captivating journey offers adventurers a glimpse into the area's rich mining history. Originally part of a narrow-gauge railroad bed that served the mining communities of the late 19th century, this trail now beckons hikers, bikers, and explorers to traverse its scenic track.

There was deep snow between waypoint 7 and 8. It was too much for my stock Wrangler.

Nice trails with some great views. Rating is accurate. Some sections are a bit harder with the amount of snow. No issues with a stock 4 runner.

Ran this today along with Gordon Gulch and part of Upham Gulch. Weather was great and sunny with a decent amount of vehicles out on the trail. Started on the East side. Fairly easy with 4wd. Snow along most of it but well packed. Snow gets a bit deeper near where this trails intersects Gordon Gulch, high clearance is recommended.

Ran this trail on holiday weekend. Was a good amount of traffic at start and finish. Nothing special about this trail, rocks most of the way and spurts of large ruts. Nothing too difficult but found the trail more annoying than challening. Ran the trail in stock Nissan xterra.

One of my first off road trails and the views were amazing! Great beginner route. 3 real obstacles with (1) a narrow tilted pass between two fallen trees, (2) a large thigh high rut that you need to avoid, and (3) a few inch high mud puddles
