Vasco Caves Regional Preserve is a beautiful and special place. It is home to rare and endangered plant and animal species, and is a native american archaeological site. Because of this, access is restricted. Hikers can only visit on a tour with the East Bay Regional Park service.
Here is the link to the East Bay Parks Vasco page. To view upcoming trips to this preserve, click here to access the activities page.
