From: Five Canyons Parkway in Castro Valley
To: Garin Regional Park in Hayward or Dry Creek Pioneer Regional Park in Union City
This long stretch of trail is primarily on old ranch roads along the main ridge above Castro Valley, Hayward, and Union City. Mostly on open grassland, the trail offers unparalleled views of the bay and its surrounding mountains, as well as views out to the east. This section is best done as a car shuttle as it is about 11 miles one-way. Two miles of the trail’s midsection pass through the Stonebrae Country Club on golf paths and roads. Because Stonebrae is a gated housing development, it cannot serve as a trailhead for the general public.
Elevation Gain/Loss 1,470 feet/1,520 feet to Garin or 1,470 feet/1,875 feet to Dry Creek
