Description Suggest change

The namesake rock of the park!

This is probably the most popular boulder in the East Bay. It’s common to see large groups of people bouldering here on weekends and there usually are at least a couple groups out on weekday afternoons/evenings as well.

Descent is a simple walk off the back using the steps.

If you're up to it, Nat's Traverse is a must do.

Getting There Suggest change

It’s the centerpiece of the park and impossible to miss!
