Best Bike Trails in Aspen
Aspen, Colorado — updated August 22, 2026
Paved valley miles, a steady climb out of the West End, and a switchbacked road with the town laid out below: the Aspen rides worth planning a morning around, with notes on seasonal closures and how settled each rating is.

Riding in Aspen splits cleanly into two kinds of day: flat paved mileage down the valley floor, and climbs that start within a few blocks of downtown and gain altitude fast. Seasons matter more here than in most cycling towns, since parts of the valley trail network shut down for the winter while the stretch inside Pitkin County stays open and groomed. The list below leans on the routes with the clearest riding evidence behind them, and flags where the review record is still thin.
1. Rio Grande Trail
This is the paved backbone of the valley and the one route on the list built for riding rather than shared with hikers by default. Reviewers describe it plainly as a nice paved trail, which is the point: consistent surface, easy to judge distance, no route-finding. Plan around the seasonal closure between Rock Bottom Ranch and Catherine Bridge, which runs from 5pm on November 30th until 5pm on April 30th. The section within Pitkin County stays open year-round and is groomed in winter. Pitkin County lists 970-920-5200 for trail questions. It holds a 4.9 across 69 reviews, a strong score on a count small enough that it could still move.
2. Hunter Creek Trail Head
Hunter Creek Trail #2194 is described as an intermediate to moderate route you can hike, run or mountain bike, and it is dog friendly, which makes it the most straightforward singletrack option starting from town. The trailhead sits on South Hunter Street, and the trail runs through a river and stream corridor in forest, with the first mile and a half or so a fairly steady climb. Budget more time than the distance suggests because of that grade. The City of Aspen Parks Department answers Monday through Friday, 7:30am to 4:30pm. Rated 4.8 from 78 reviews: consistent, though not a heavily reviewed listing.
3. Smuggler Mountain Trailhead
The draw is the payoff for the effort: reviewers single out the views over Aspen and the surrounding valley from the climb. The route is wide for most of its length and largely paved, which makes for a predictable surface and room to pass on a busy morning. The City of Aspen rates Smuggler Mountain Road as moderate. Parking is on County Road 21 and fills early on summer weekends, so an early start does double duty for shade and a space. Parks Department hours are Monday to Friday, 7:30am to 4:30pm. At 4.7 across 89 reviews, it has the largest sample of the in-town climbs here.
4. Castle Creek Trailhead
The quietest option on the list, and the one with the least evidence behind it: 4.7 from 31 reviews, enough to suggest people leave happy but not enough to call settled. Reports from the trailhead describe conditions beyond the parking area as rough and slow going, with a creek crossing that has run low and been easily passable. Dispersed campsites nearby have been subject to seasonal closures, so check current status before planning an overnight. Treat this as a ride out Castle Creek Road for the corridor itself rather than for maintained singletrack, and go with tires and gearing that can handle uneven ground.
