$10 per vehicle park entrance fee.
Mount Diablo State Park
Walnut Creek, Contra Costa County

Join us for a late afternoon/early evening hike on the Mary Bowerman trail. We’ll circle the top of Mount Diablo and see the rocks, faults, and views that have fascinated geologists since the 1860s. As we walk, we’ll see all nine Bay Area counties where Greenbelt Alliance works.

After our hike, you can stay for the monthly astronomy night on top of the Mount Diablo for some serious star and planet gazing. Heavenly bodies visible this night include Venus, Jupiter, Saturn, and Mars.
