A Guide to Calaveras Big Trees State Park

Ever dreamt of being transported to the land of giants? Calaveras Big Trees State Park can make your dream come true. Home to two imposing groves of giant sequoias, the state park was established in 1931 to preserve the glorious stand of towering trees. Calaveras State Park is the main attraction of Calaveras County, where beautiful landmarks, rolling hills, and giant valleys dominate the area. 

Walking among the sequoias at the state park reminds us of the chapter in Alice in Wonderland when Alice drinks the potion and shrinks—next to these mighty sequoias, you too will feel smaller and smaller until at last, you’re just the size of a little doll. Undoubtedly one of the most underrated state parks in California, Calaveras Big Trees State Park is definitely worth the visit.

Everything You Need To Know About Calaveras Big Trees

Augustus T. Dowd is credited for the discovery of the North Calaveras Grove in 1852 when he was tracking down a bear. But this wasn’t the first discovery of the giant trees. In 1833, a group of hunters made a reference to the sequoias without any mention of the locality; the reference was found in explorer J.K. Leonard’s diary but wasn’t publicized. John M. Wooster, another person who discovered the North Grove, carved his initials in the bark of the Hercules tree in 1850. However, he also didn’t receive any publicity. 

The old sequoia discovered by Dowd was dubbed the “Discovery Tree.” This giant sequoia was felled in order to take it on a tour around the world. Before long, the Discovery Tree became a worldwide sensation. Measuring 25 feet in diameter at its base, the sequoia was estimated to be 1,244 years old at the time of its felling. The giant stump left was turned into a dance floor—this was highly criticized by the Father of National Parks, John Muir.   

The second tree to be felled was the Mother of the Forest. This ancient and colossal sequoia met its demise in 1854 when the 2,520-year-old tree was stripped of its first 100 feet of bark. By 1861, the Mother of the Forest shed its entire canopy; its dead remains are found at Calaveras Big Trees Park, where visitors can easily view the saw marks on the trunk. 

Back in the day, the towering sequoias were a great source of lumber. Multiple lumber companies had plans to cut down the remaining trees in the area. The destruction of the sequoias was met with public outcry—locals and conservationists had had enough. They strongly expressed their disapproval and anger regarding the trees' treatment, and in 1931, Calaveras Big Trees State Park was finally established in order to protect and conserve the remaining sequoias in the area. Now, the state park encompasses 6,498 acres in Calaveras and Tuolumne Counties.

Calaveras Grove

There are two groves at the state park: North and South Calaveras Groves. There are approximately 100 mature trees in the North Grove and around 1,000 trees in the South Grove. 

The Discovery Tree and the Mother of the Forest were both located in the North Grove. Now, all you see is the stump where the largest tree in the park once stood and the Mother of the Forest’s fire-blackened snag. 

Pioneer Cabin Tree, another giant sequoia located in North Calaveras Grove, also met its demise on January 8, 2017. Known as the “Tunnel Tree,” it was only one of the two living giant sequoia tunnel trees that still stood. Pioneer Cabin Tree collapsed during a storm—the tree had already been weakened due to the severe damage caused by hollowing out its trunk. Now, the largest tree of North Calaveras Grove is the Empire State, which measures 30 feet at ground level. 

South Calaveras Grove includes Louis Agassiz, the 37th largest sequoia in the world. As the largest living tree of the Calaveras Groves, Lous Agassiz measures 250 feet tall and over 25 feet in diameter. Another noteworthy giant in South Grove is the Palace Hotel Tree, the second-largest living tree in the groves. Palace Hotel Tree has a large and deep burn scar at its bottom, which you can easily walk into.
