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 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.
