WHY IT’S FUN
A route with a reason.
The Rio Grande Trail follows the historic Aspen Branch rail corridor for about 42 miles between Glenwood Springs and Aspen. It is continuous and mostly separated from traffic, but the direction matters: Aspen sits roughly 2,100 feet above Glenwood Springs. Most of the trail is paved, with about two miles of crusher-fine below Stein Park.
Source-backed, not locally verified: This is an editorial guide, not live navigation. Check closures, detours, weather, traffic and access rules with the source immediately before riding.
Where the ride looks best
The upper valley between Basalt, Woody Creek and Aspen is the most cinematic, with the Roaring Fork River, ranch meadows, cottonwoods and mountain views. The Catherine Bridge–Rock Bottom Ranch wildlife section is especially peaceful when seasonally open.
Where to stop
Plan one deliberate stop around the route’s main rail trail feature, then keep the remaining schedule flexible.
Who to ride with
Ideal for riders who prefer changing scenery and a point-to-point story over technical riding. Friends and couples can share logistics; experienced solo riders should carry repair supplies. Families should choose a shorter section around Glenwood Springs, Carbondale, Basalt or Aspen.
The story behind it
Its former railway alignment explains the steady grade, direct line and pieces of transport heritage that still shape the ride.

BEFORE YOU RIDE
Useful beats heroic.
Safety
Keep right, ride single file, announce passes and observe RFTA’s 20 mph maximum. Everyone yields to horses. Expect pedestrians, dogs and children near towns; stop off the travel lane. Cross roads cautiously even when the trail appears to have priority. Carry lights if timing could extend toward dusk.
Weather & season
Choose a stable forecast and enough daylight for the planned distance.
Water & supplies
Start with water even on short routes; confirm taps, cafés or seasonal facilities rather than assuming they are open.
Public transport
Check local transit bicycle rules and service changes for Aspen to Glenwood Springs, Colorado; Tour de Fun does not verify carriage restrictions or last services.
Parking
Two Rivers Park and several mapped trailheads provide parking, but capacity, event restrictions and overnight rules vary. Herron Park has limited parking. For a one-way ride, confirm legal parking at the chosen start and avoid leaving valuables visible.
Local riding rules
Keep right where required, signal before passing, yield according to local signs, use lights in low visibility and respect pedestrian, wildlife and e-bike rules published by the route authority.
