Diver Information
Whether you're visiting Caspar Cove for the first time or you've been diving these waters for years, we're grateful you're here.
Our community of volunteer divers plays an important role in helping restore Northern California's underwater forests by reducing the number of overabundant purple sea urchins in key restoration areas. Every dive contributes to a larger effort to give bull kelp—and the incredible ecosystem it supports—a chance to recover.
