Calaveras Big Trees State Park is a big outdoor place where you can go see very big trees. It's like a really big forest where the trees are super big and tall, and some of them are really old. People go there to see the trees and enjoy nature.
The big trees in the park are called Sequoias and they are some of the biggest trees in the world. They can grow to be as tall as 26-story buildings! They are also really wide and can be bigger than a school bus!
When you go to the park, you can take a walk on a path that goes through the trees. You might see some animals like squirrels, deer, or maybe even a bear! You can also have a picnic there and eat lunch outside in the fresh air.
Overall, Calaveras Big Trees State Park is a cool place to visit if you want to see huge trees and enjoy nature.
