Calaveras Big Trees State Park is celebrating 90 years of Wonder on Thursday, June 24, 2021. 90 years ago to the day, we became a State Park. Please come on that day to help us celebrate. There will be activities including Jr. Rangers and Cubs, a scavenger hunt with prizes, crafts for the kids, plus more surprises. The fun will be between 10 and 3. Please come celebrate with us as we honor 90 years of the amazing park!
