The Rim Trail, right outside of Snowmass Resort, is a beautiful, non-technical loop with fun, swooping single track and mind-blowing views of the snow-capped Rockies. This is great trail for beginner riders or anyone looking for a fun, not-too-challenging ride. The climbs are well built and very rideable, and the descents are smooth and fast.
Start at the Divide Road parking lot on Divide Road, right off of Brush Creek Road. From there, climb up smooth singletrack to the summit. The climb is nicely graded and not too difficult, even with limited oxygen at 8,000 feet. At the summit, take a left and climb for an extra 100 meters to a lookout point with a phenomenal 360 degree view. From there, prepare for a ripping fast descent with a few steep, punchy climbs. The descent will take you to a road crossing, where you can bail out to make a shorter ride, or you can continue across the parking lot for a second climb. This second climb is steeper and more exposed than the first, but still enjoyable.
The trail traverses along a ridge line with spectacular views of Snowmass Valley and Resort, before descending through aspens & sage meadows and ending up back at the Rodeo Parking Lot in Snowmass Village. This descent is even faster than the first, but be prepared for tight, sandy switchbacks that will cut your speed. It's easy to go too fast into these turns and ride off the trail. From the Rodeo parking lot, take the Brush Creek Bike path until it ends and then hop onto to Brush Creek Road back to your car.
