Tassajara Creek Trail
The Tassajara Creek Trail is located in the southeast portion of Mount Diablo State Park (MDSP), between Highland Ridge Road and Riggs Canyon Road. The original 1.25 mile section of the trail, which largely runs parallel to the Tassajara Creek, was build by the East Bay Trail Dogs in 2003. At that time the property (known as the “Silva property”) was owned by Save Mount Diablo, but was later transferred to MDSP. This original section of the Tassajara Creek Trail has also been referred to as the “Trillium Trail” due to the abundance of Trillium plants growing alongside the trail.
In 2009, at the request of MDSP, the East Bay Trail Dogs built a 0.75 mile extension of the Tassajara Creek Trail to bypass most of the (now-abandoned) Bob’s Pond Fire Road. A picnic table, also built by the East Bay Trail Dogs, is located where the original and new sections of the trail meet, overlooking Bob’s Pond.
The featured hike for the Tassajara Creek Trail is a moderately challenging 6.35 mile hike with a total elevation gain of 1,785 feet. Click here for directions to the trail head, hike details, a satellite view, and a Topo map with elevation profile.
