Mount San Jacinto State Park is a California state park that protects the high elevations of the San Jacinto Mountains near Palm Springs. The park includes alpine and subalpine habitats and access to trails that reach the park’s high peaks.
Hiking, backpacking and rock climbing are primary activities, with trails that ascend from valley trailheads into mountain meadows and forests, providing cooler temperatures and panoramic views compared with the surrounding desert. The park is a popular destination for day hikes and overnight climbs to the higher summits.
The park was established to conserve the San Jacinto high-country and to provide managed public access to its trails and peaks. Management focuses on trail maintenance, visitor safety and protecting high-elevation ecosystems.
Mount San Jacinto State Park lies inland from the southern California desert communities, adjacent to the city of Palm Springs, and protects the western slopes of the San Jacinto range.
- Aerial tram access: The Palm Springs Aerial Tramway provides convenient access from the desert floor to high-elevation trails and is a common route for day visitors to the park.
- High-elevation hiking: Trails lead to San Jacinto Peak and high alpine terrain, offering cooler conditions and panoramic views compared with the nearby desert lowlands.
