This year Mount Diablo State Park turns 100, which means it is time for a party!

You are invited to help celebrate the park's centennial at a special event on Saturday, October 16th, 10:00 AM - 4:00 PM at the foot of the mountain at Cal State East Bay's Concord Campus.

Activity booths will showcase the park's fascinating wildlife, history, and ways to safely enjoy the park. Discover the variety of creatures tha call the park home as you meet live animals such as bats, snakes, and local birds of prey. Meet the volunteers and horses of our Mounted Assistance Unit who roam the trails on horseback. Discover why the oldest rock layers are at the top of the mountain, and see how astronomers view the heavens from the mountain's height.

California State Parks and its partners the Mount Diablo Interpretive Association, Save Mount Diablo, and Cal State East Bay hope you will join us for this event to celebrate Mount Diablo State Park's birthday, its many stories, and the community connection to this amazing place.
