Four Mile Trail
A steep climb from Yosemite Valley to Glacier Point, views the whole route.
About
Four Mile Trail is the classic — and brutal — connector between Yosemite Valley and Glacier Point, climbing switchback after switchback with views that keep getting better the higher you go. It's steep and exposed in places, but it delivers some of the best panoramas in the park: Yosemite Falls, El Capitan, Sentinel Rock, Half Dome, and Tenaya Canyon all show up along the way.
What to expect
The round trip runs 9.6 miles with about 3,200 feet of elevation gain on the climb back up to Glacier Point, and the National Park Service calls it a steep, all-day hike — plan on 6 to 8 hours. The "four mile" name is a holdover from before the trail was rerouted; one-way is closer to 4.8 miles today. Most people hike it as a one-way trip between the Valley and the Point rather than out-and-back.
Getting back down
- There is no shuttle between Yosemite Valley and Glacier Point — if you go one way, you either hike back or arrange your own transportation.
- Glacier Point Road, which reaches the upper trailhead, is typically open late May through October or November; call the park at 209-372-0200 to confirm current conditions before you go.
- Water is only available seasonally at Glacier Point and not at all at the Valley trailhead, so carry what you need.
- Pets and bicycles are not allowed on the trail.
