Sequoia National Park
Park Mountain park protecting giant sequoias and deep canyons
Home to giant sequoias including the General Sherman Tree, Sequoia National Park offers mountain trails, granite peaks and caves; visitors hike among ancient trees and explore the southern Sierra Nevada.
Sequoia National Park in California is a federal park created to protect groves of giant sequoias and high Sierra landscapes; it was established in 1890 and is best known for its enormous trees. The park preserves old-growth forest, alpine terrain and deep granite canyons.
The park’s headline attraction is the giant sequoia groves, including the General Sherman tree, noted as the largest known single-stem tree by volume. Visitors also use short trails and overlooks such as Moro Rock for panoramic views and access to the forested high-country.
Protected at the end of the 19th century specifically to conserve sequoia trees from logging, the park has been managed to balance visitor access with conservation of ancient groves and natural fire regimes. Infrastructure and trails have been developed to concentrate visitation and protect sensitive areas.
Sequoia National Park lies in the southern Sierra Nevada of eastern California, with park roads and trailheads accessed from mountain towns such as Three Rivers and by routes ascending from the western San Joaquin Valley.

How to Get to Sequoia National Park #
By car: the primary western approach to Sequoia National Park is from Visalia via California State Route 198 to the Ash Mountain entrance - this is the most direct gateway and typically about a 1‑hour drive from Visalia. Another common approach is from Fresno via CA‑180/General’s Highway; roads inside the park are steep and winding and can be restricted in winter, so check conditions before travel.
Within the park: major groves and trailheads require additional short drives from the park entrance and have parking at trailheads (e.g., Giant Forest area).
Tips for Visiting Sequoia National Park #
- For the General Sherman Tree and Giant Forest, arrive at opening or later in the afternoon to avoid the busiest hours; parking lots are small and fill early in peak season.
- Check road and trail conditions before you go-Generals Highway and high-elevation roads can close seasonally for snow or maintenance, so verify current status with the park website or visitor centers.
- If you plan to tour Crystal Cave, book a guided tour in advance and note it's only open seasonally; many visitors miss the cave because they don't reserve the limited tour spots.
