No, this loop is considered challenging and is recommended for intermediate to advanced mountain bikers. The Government Trail itself is a black diamond-rated singletrack with technical sections, while the Buttermilk Mountain portion includes steep climbs and potentially rutted, challenging descents with rock ledges.
The terrain offers a full range of challenges. The Government Trail features rocky sections, stream crossings, switchbacks, root ledges, and steep climbs and descents. The Buttermilk Mountain section involves a significant and steady climb up a summer work road, followed by singletrack descents that can be rutted and include 1-3 foot rock ledges.
The trail is best ridden outside of the elk calving season. A portion of the Government Trail is typically closed from May 15 through June 27 or 28. Check local conditions before you go, but generally, late spring (after closures lift), summer, and early fall are ideal.
You'll experience abundant scenery, including numerous aspen groves, flower-filled meadows, and scenic mountain range overlooks. Climbing Buttermilk Mountain offers excellent views of the Maroon Creek valley, Pyramid Peak, and the wider Roaring Fork Valley. Don't miss the Viewing Platform on Buttermilk Summer Road.

Look out for the "Rock Garden" just before entering the Buttermilk ski area slopes, and "The Root," a gigantic tree with massive roots in the middle of a switchback that offers a more daring line for skilled riders.
While it can be ridden in both directions, the Government Trail is typically ridden from Snowmass to Buttermilk/Aspen. This direction generally offers more descent, making for a more flow-oriented ride.
Yes, the route incorporates sections of several other trails. You'll ride parts of the Buttermilk Summer Road, Government Trail, Buttermilk Ridge, Maroon Creek Trail, and Moore Trail, among others.
