Aspen Snowmass IMBA Epic Loop

Mountain Biking Trail

An incredible Mega Loop that's 95% on singletrack!

The Aspen/Snowmass IMBA Epic Loop, also known as the “Mega Loop,” is an almost 60-mile loop incorporating many of the very best trails in the Roaring Fork Valley. On this ride you’ll tackle local classics like [Smuggler Mountain]( the [Rim Trail]( [Government Camp]( and so much more… and then combine them all into one massive freaking loop.

On this ride, you’ll encounter everything from "aspen and dark timber forests to sage fields and grassy meadows bursting with wildflowers,” according to the [Roaring Fork Mountain Bike Association (RFMBA)]( "From flowing on ribbons of smooth dirt, to negotiating the rock gardens of the famous local classics, finishing this ride in a day rewards those with patience, fitness, skill, and experience,” they continue.

The vast majority of this ride is buff, smooth singletrack, but a few of the local classics provide some spice and challenge. Government Camp, in particular, is home to some seriously-chunky rock gardens and technical stream crossings. In addition, the trail tread on the Sunnyside trail is ridiculously narrow, with the steep mountain slope providing a very real fall danger.

If you’re willing to brave the challenges, this Mega Loop will offer up a rare long-distance ride that’s about 95% on singletrack. There are few places in the nation where you can pedal anything remotely like this!
