Yosemite National Park: Glacier Point to Four Mile Trail - Backpacker

Yosemite National Park: Glacier Point to Four Mile Trail

Notch inimitable panoramas of Yosemite Valley from the soaring Glacier Point before tackling a steep descent from the South Wall on this staggeringly scenic 4.6-miler.

If Yosemite National Park had a hall of fame, it would rest atop the towering crags of Glacier Point. The high-country vantage point, perched upon a dizzying precipice along Yosemite’s South Wall, offers jaw-dropping panoramas of some of the Valley’s most recognizable features: Half Dome to the northeast; Vernal and Nevada Falls above the Merced River and Illilouette Gorge to the east; Yosemite Falls across the valley to the north; and the Clarke Range across the southeastern horizon. You’ll likely bump elbows with a few tourists at the magnificent viewpoint, but crowds disappear as you begin a descent to the Valley floor via the scenery-laden Four Mile Trail.
Dropping nearly 3,200 feet from the rugged South Wall, the trail starts by ducking into a shady grove of sugar pine and white fir trees. The forest soon gives way to a series of exposed, sun-drenched switchbacks offering fresh-angled panoramas of the Valley below. Upon sweeping back into a wonderland of black oaks, Douglas-Firs and incense-cedars, the trail hugs cliffsides before settling into a steady descent culminating at the valley floor. The hike ends with a view of the majestic Sentinel Rock from the Four Mile Trailhead at Southside Drive.
Getting to and from the trailhead is tricky, as Yosemite’s free shuttles don’t go to Glacier Point. The park does offer a shuttle from Yosemite Lodge, but the one-way trip costs $25 and takes two hours, due to frequent stops for photo opportunities. With two cars, it’s possible to leave one at the Glacier Point and one at Southside Drive (the trailheads are separated by 27 miles of road and about one hour of driving). Otherwise, you can turn the trip into an out-and-back by climbing back from the Valley floor to Glacier Point. Information on the Glacier Point Shuttle is below.
