Hiking
Maroon Bells is the essential Aspen hike. Shuttle reservations required in summer. The full Maroon Bells guide covers access, trails, and photography tips.
Hunter Creek Trail starts from downtown and climbs through aspen groves to high meadows. Multiple loop options from easy to challenging. No shuttle needed—walk from town.
Sunnyside Trail loops around Aspen Mountain with gondola access for one direction. Views of the town below and Elk Mountains beyond. Moderate difficulty with manageable elevation gain.
Cathedral Lake is a challenging 6-mile round trip to an alpine lake beneath Cathedral Peak. Significant elevation gain but spectacular payoff. Full-day commitment.
Biking
The Rio Grande Trail follows the old railroad grade from Aspen to Glenwood Springs. Mostly paved, mostly downhill if you start from Aspen. Shuttle services available for one-way rides.
Mountain biking on Smuggler Mountain, Sky Mountain Park, and the Government Trail network offers terrain for all levels. Aspen Highlands operates lift-served biking in summer.
Road cycling up Independence Pass challenges serious riders with 4,000+ feet of climbing. The descent is unforgettable. Less ambitious routes follow the valleys in any direction.
Fly Fishing
The Roaring Fork River runs through downtown Aspen, offering walk-to fishing access. Gold Medal waters hold healthy trout populations. Catch-and-release sections ensure quality fishing.
The Frying Pan River below Ruedi Reservoir is famous for large trout and technical fishing. Tailwater conditions create year-round hatches. Some of Colorado's best fly fishing.
Guide services operate throughout the valley. Half and full-day trips for all skill levels. The guides know the hatches and the water—worth the investment for serious anglers.
Rafting & Water Sports
The Roaring Fork offers Class II-III rafting depending on section and water levels. Family-friendly stretches and more challenging rapids coexist. Multiple outfitters run trips.
The Colorado River near Glenwood Springs provides bigger whitewater. Shoshone section delivers consistent Class III rapids. Day trips from Aspen are popular.
Stand-up paddleboarding on calmer stretches of the Roaring Fork or at area lakes provides gentler water recreation. Rentals available in town.

Aspen Music Festival (late June through August) brings eight weeks of classical performances. Free and ticketed events. The whole town becomes musically charged.
Aspen Ideas Festival (late June) gathers thought leaders for a week of substantive programming. Registration is expensive but content reaches broader audiences through media.
Food & Wine Classic (mid-June) celebrates culinary excellence with tastings, seminars, and events. Tickets are competitive and pricy but the experience is unmatched.
