(California)
Calaveras Big Trees State Park is a state park of California, United States, preserving two groves of giant sequoia trees. It is located 4 miles (6.4 km) northeast of Arnold, California in the middle elevations of the Sierra Nevada. It has been a major tourist attraction since 1852, when the existence of the trees was first widely reported, and is considered the longest continuously operated tourist facility in California.
