Calaveras Big Trees State Park is a California state park in the Sierra Nevada foothills that protects two groves of giant sequoia and associated mixed-conifer forest. The park is focused on conserving these large sequoias and providing trails, campgrounds and interpretive resources.
The principal attractions are the sequoia groves and the network of trails that pass notable trees and interpretive signs; camping, picnicking and guided natural-history programs are typical visitor activities. The park’s trails range from short interpretive loops to longer hikes through the surrounding forest.
The park was set aside to protect the groves from logging and to provide public access to these large trees; its management balances conservation with outdoor recreation. It lies along the Sierra Nevada foothills in Calaveras County near small mountain communities and is accessed from the regional highway network.
- Seasonal access: Road and trail access can be limited by snow in winter; summer and early fall are the most reliable seasons for ungated access and hiking.
