Recreation

Yosemite's trails, cliffs, roads and rivers provide endless recreational activities for any kind of visitor. Hiking, biking, rock climbing, fishing, horseback riding, rafting, auto touring, and photography are all very popular activities within the park. The White Wolf area has hiking and backpacking opportunities that begin near the campground, such as Lukens Lake, Harden Lake and the Grand Canyon of the Tuolumne. The Crane Flat area, 23 miles west, offers many other hiking opportunities such as Tuolumne and Merced Groves of Giant Sequoias, both of which require a 2.5 to 3-mile roundtrip hike to view. Tuolumne Meadows and all it's High Sierra wonder lie 25 miles to the east, where many beautiful day and overnight excursions await.

The Tioga Road offers a 39-mile scenic drive past forests, meadows, lakes, and granite domes. The road’s elevation ranges from 6,200 feet to just under 10,000 feet. Tuolumne Meadows embodies the high-country of the Sierra Nevada and is a good starting point for countless hikes. There is little to no cell service along the road.
