Access the South Fork Tuolumne River wilderness trailhead from Tioga Road. No developed lot is identified in the trailhead information; confirm the legal roadside access before starting.

Yosemite National Park, CA
A quiet forest descent to the South Fork Tuolumne.
Overview
This is a 5.8-mile out-and-back from the South Fork Tuolumne River trailhead on Tioga Road to the river and back. The published route description gives 2.9 miles each way; the available map line is about 2.5 miles to the river, so plan around the longer figure. The trail drops roughly 1,180 feet to the river, then climbs that ground again on the return. Allow about four to five hours, especially if you need time to keep the faint route in view. This suits hikers comfortable navigating a lightly used wilderness trail.

Trail guide
The path winds through old burn areas and mixed conifer forest. It sees little traffic, and the tread can be difficult to follow. Keep a detailed offline map available and turn around if you lose the line. The South Fork is the destination for this outing; the longer route onward to Aspen Valley is a separate backcountry commitment.
