Trail Information
The trail to Mount Olympia is arguably the steepest trail in the Mount Diablo State Park. The first part of the trail from Three Springs 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. 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.
Turn right at first road junction and soon there after right onto a small trail. At its end make a short left jog on the gated road to locate the posted Olympia Trail. Follow it and its continuation, the East Trail, to the summit.
Directions
The trailhead is located on the right side of Marsh Creek Road about two miles beyond Regency Drive in Clayton.
