Come volunteer with us! 

Calaveras Big Trees State Park is the only California State Park with giant sequoias, the biggest individual tree. Volunteers increase the ability of park staff to provide a high-quality experience at this unique park to over 200,000 visitors a year! Volunteers come from diverse backgrounds, with individual preferences, talents and interests. Some enjoy working behind the scenes, while others prefer meeting the public when hiking trails or interacting with adults, school groups, and families. There are many benefits to those who choose to volunteer, such as training, use of the park, passes to other California State Parks, and – best of all – camaraderie, friendships, and satisfaction. 

All long-term volunteers must come to a volunteer orientation, often held the last weekend of March. For 2026, sign ups for Orientation are due on March 23, 2026 and the Orientation will be held March 28th and 29th. Optional trainings on the different possible tasks, such as invasive species management, trail roving, school tours, and summer programs are often held on weekends in April.
