Meet at the unnamed trailhead on right hand side of Morgan Territory Road, immediately after the junction with Marsh Creek Road (look for a large blue building on the right and park in dirt lot on the right). There will be a 5-mile carpool from here to the Red Corral trailhead on Morgan Territory Road which has extremely limited parking.


This hike explores the hills framing Riggs Canyon in the southeastern reaches of Mount Diablo State Park. We’ll make our way to Bob’s Pond just below Windy Point for lunch and then descend the shady Tassajara Creek Trail into lower Riggs Canyon. We’ll then ascend Highland Ridge for stunning views of the Diablo summit and North Peak. Wildflowers should be abundant. Allow 8 hours (from the parking lot) for this 10.5 mile hike with a total elevation gain of about 2100 feet. This hike has a steady relaxed pace with a 30-minute lunch and other rest breaks. Be prepared for mud and poison oak. There is no restroom at the trailhead. Any rain cancels.
