Everyone is welcome (dogs optional).

The East Bay hills are at increasing risk of wildfires due to our changing climate. Learn about our research to help the Bay Area prepare.

NOTES

Bring snacks, water, hiking poles (if you normally use them), and a leash (if bringing a dog); wear layers and good hiking shoes. East Bay Regional Park District rules allow dogs off-leash in much of the park, provided they are in sight and under voice command. However, dogs must be leashed within 200 feet of developed areas.
