One of the fiercest peaks in the Bay. Always worth the effort. Itβs often much cooler on the summit than the rest of the trails β there is a water spigot up there to fill up bottles. Also a store is open at some times. Donβt bank on it.

Carquinez Scenic Drive, a once popular roadway for cars, has been closed since the 1980s due to landslides that caused damages. However, the former road has now been transformed into a beautiful paved park trail in the Carquinez Regional Shoreline Reserve on the east, and a well-rebuilt paved bike path on the west of the oil dock. The trail is a great spot for biking and offers a shaded area with several scenic viewpoints that overlook the stunning bay.
