The world’s largest trees lie within Sierra Nevada mountains just 4 miles northeast of Arnold and 76 miles northeast of Modesto. Calaveras Big Trees State Park serves to protect these ancient sequoia trees (thought to be at least 2,000 years old) and has done so since the California state park was first established in 1931.

Visitors have been attracted to these magnificent trees since 1852, and today enjoy exploring the miles of trails that wind through the North and South Groves and along the Stanislaus River and Beaver Creek. The park also features scenic picnic areas, two large campgrounds, rustic cabins, a Visitor Center, Museum, and Bookstore.


Imagine what the earth looked like thousands of years ago with a visit to serene Calaveras Big Trees State Park. Pack your overnight bag and binoculars and prepare to spend a few peaceful days and nights surrounded by ancient sequoia trees and majestic mountain tops.

Be sure to save some time aside for a visit to the Museum (admission is included in your park entrance fee), located inside the Visitor Center. Here you will find hands-on exhibits, wildlife displays, and more that showcase the park’s flora, fauna, and history. Then check out the Visitor Center Bookstore’s wide range of books and souvenirs.
