Mt. Olympia Summit/Bruce Lee Spring Trail Loop

City: Clayton
Park: Mt. Diablo State Park

Saturday, July 21, 2007 @ 9:00 AM

Event Notes:

Meet at the end of Regency Drive. There are many things to attract your attention on the way and to let you catch your breath - wildflowers well into summer, grotesquely eroded rock formations reminiscent of the American Southwest, the sequence of gradually expanding views. The climax view, of course, is from the summit itself. Stop at the summit for a snack/lunch. Mt. Olympia is one of the park's prime destinations, a rugged outcrop with fantastic views of dizzying canyons, particularly with the mists of winter. Mostly shady, this is particularly desirable in July. Approximately 9 miles, with a 2900 foot elevation gain.

Trail Notes:

From Regency Gate, follow Donner Canyon to Cardinet Oaks Road. From there, climb Olympia Trail to Mt. Olympia Road and the Olympia Summit Trail to the summit. This is arguably the steepest trail in the park. The first part is gentle enough, but things get a lot more challenging when you get to the flanks of Mt. Olympia - the total rise occurs in a little over a mile. Return down from Mt. Olympia Trail to Cardinet Oaks Road, and then take the Wasserman Trail to Bruce Lee Spring Trail, crossing the spring back to Donner Canyon. Approximately 9 miles, with a 2900 foot elevation gain.
