The 5 Best Mountain Bike Trails Around Grand County

Mountain bike trails in Grand County do more than challenge your legs—they connect you to alpine draws, hidden water crossings, and terrain that tests your flow. The Best of Grand contest spotlighted trails that deliver for every rider: from mellow loops to flow lines and technical climbs.

Flume Trail

Flume is a scenic singletrack that parallels St. Louis Creek, named for an old logging flume that once ran along the path. The route features a moderate climb and sections of flowing descent with enough twist and terrain change to keep things interesting. Riders often extend it via Creekside Loop for a more substantial ride.

Phases Trail

The Phases network in Tabernash is a rebuilt, multi-trail system known for good flow and varied terrain. With about 14 miles of trail, it includes jump features, technical connectors, and “classic” segments carved into forest and layered terrain. Riders often praise it as one of the first high-elevation trail systems to open in spring.

Saint Louis Creek / St. Louis Creek Trails

Although less formally mapped than some, trails near St. Louis Creek (including the Flume corridor) provide shaded, creek-adjacent singletrack that appeals to riders wanting scenic quiet and moderate challenge. Its proximity to Fraser and Winter Park makes it a beloved local option.

Twisted Ankle Trail

Part of the Fraser Valley trail network, Twisted Ankle is mentioned in local listings as an intermediate line with some technical features and flow for riders who want a bit more pedal without going full downhill. It’s often grouped with other valley flow trails in trail guides.

Wolford Mountain Loop

Wolford Mountain Loop is a wider, regional route that balances climbing, ridge-line views, and backcountry access. While not as frequently mapped in the immediate Winter Park/Fraser guides, it's included in Grand County MTB networks and regional route maps.
