Overview

From the small parking area on Tunnel Road at the north trailhead of Sibley Volcanic Preserve, Skyline Trail climbs to cross over the Caldecott Tunnel a few yards back from its portal, hidden in dense foliage. Part of the Bay Area Ridge Trail, it’s a narrow track over forested and grassy watershed slopes, linking Sibley Preserve to Tilden Park two miles north, offering long views of Mount Diablo and Sibley’s Round Top, with a good chance of spotting a jackrabbit or a coyote. On the way to Tilden’s Steam Trains it crosses Fish Ranch Road and later overlooks Grizzly Peak Blvd.

Details: There’s a vault toilet at the trailhead; no fees; bikes and dogs are not permitted and it’s too narrow for a wheelchair.
