East Bay: Canine Caper

Sunday, June 9, 2019
9 a.m. - Noon
Free; RSVP Required.
Sibley Volcanic Regional Preserve
Oakland, Alameda County

Bring your four-legged friends (two-legged friends also welcome) for a nature hike in the Oakland Hills.

Ten million years ago, a geologic convergence called the “triple plate junction” produced the volcanic features seen in the park today. But what strange convergence of forces produced the park’s stone labyrinths? Canine detectives are on the case!

Bring snacks, water, hiking poles (if you normally use them), and leash (if bringing a dog); wear layers and good hiking shoes.
