Bouldering too!

Beautiful! Some parts very muddy but mud doesn't scare me. Passed a lovely brook flowing down the mountain. Cool views of the bay and San Quentin. Many talc rocks along the way. Rock carvings and formations built by Natives long ago. Saw Oakland star tulips and other beautiful wildflowers.

It's a great hike, and fairly easy trail (though it's quite slippery and muddy the day after rain). The trails are easy to follow and the views are pretty spectacular from the top of each section of the trail - from downtown San Francisco and the Bay Bridge to San Quentin Prison across the Bay and rolling green hills with rocky outcroppings and wildflowers.
