The Fossil Gap Trail, in the White Mountains National Recreation Area, is maintained for winter recreation including snowmobiling, skiing, dog mushing, snowshoeing, and fat-biking. 

The trail crosses open meadows and then follows Fossil Creek drainage downstream for approximately 1.5 miles before climbing off the creek and back into the spruce. The trail parallels the Fossil Creek before crossing open meadows to Beaver Creek. Beaver Creek has sections of overflow and open water even during winter. The trail continues through spruce forests and across the bridge at Montana Creek to the junction with Colorado Creek Trail. 

The Fossil Gap Trail is non-motorized only during the summer, May 1 - October 14. Only the southern portion of the trail from Beaver Creek to Caribou Bluff Cabin is suitable for hiking, which is a popular day hike while on a float trip down Beaver Creek Wild and Scenic River.
