Yellowstone National Park, WY · MT · ID
Meadows and creek bends make this long backcountry walk worthwhile.
Overview
Past the main ford, Fan Creek meanders through a long, nearly level meadow valley. Gaps in the pines look up the valley toward Joseph Peak. The trail rolls on to the WC3 campsite spur at about mile 4.7; turn around there for the route represented here. The WC2 and WC3 spurs lead to backcountry campsites, and overnight camping requires a permit. For a photo, frame one of Fan Creek’s bends with the meadow and far tree line so the looping water reads clearly.

Trail guide
Fan Creek Trail is a backcountry out-and-back from Fawn Pass Trailhead through forest and open meadow to the Fan Creek valley. The longer walk to the WC3 campsite spur is about 9.6 miles round trip; allow about six hours, with roughly 1,000 feet of climbing. The grade is mostly gentle and rolling, and the reward builds as the valley opens rather than arriving at one summit or waterfall. A shorter 2.4-mile return to the Fan Creek junction is an early turnaround; it skips the main creek crossing and most of the valley.
The route starts on Fawn Pass Trail, dropping toward the Gallatin River meadows and crossing the river on several short footbridges. It then climbs gradually through open lodgepole pine, with Fan Creek nearby but often hidden by trees. At about 1.3 miles, leave the right-hand Fawn Pass route and take the left branch toward Fan Creek; Fawn Pass continues uphill to the right.
An unnamed tributary crossing comes around mile 1.9, followed by the WC2 campsite spur near mile 2.5. At about mile 2.9, the unimproved Fan Creek ford is the toughest part of the walk. One late-July account describes knee-deep water; spring snowmelt can make the crossing dangerous. Check current water conditions before committing. Beyond it, the trail winds through a wooded ravine, climbs along the hillside, then crosses another tributary around mile 4.1.
Grizzlies frequent this area. At the Fawn Pass access, the park recommends groups of four or more; from May 1 through November 10, travel is restricted to designated trails. Carry bear spray and know how to use it. Pets are not allowed on park trails.
