Question: where are the sequoia trees?
Answer: Massive, ancient giant sequoias live in three groves in Yosemite National Park. The most easily accessible of these (spring through fall) is the Mariposa Grove near the park's South Entrance, off of the Wawona Road (Highway 41). Two smaller—and less visited—groves are the Tuolumne and Merced Groves near Crane Flat.
