California offers an unparalleled diversity of dive sites — from dense kelp forests and hidden wrecks to steep walls, sea caves, and marine reserves. Whether you're a seasoned diver or just beginning your underwater journey, these waters provide something for everyone. At Eco Dive Center, we guide groups aboard our boats into some of the best spots along the California coast and beyond — and none are more spectacular than the Channel Islands.

Why Dive the Channel Islands?

The Channel Islands (often dubbed “California’s Galápagos”) are a marine sanctuary teeming with life, thanks to their position at the boundary of cool upwelling waters and warmer southern currents.

Dive conditions can be challenging — currents, surge, variable visibility, and colder water are to be expected — but that’s precisely why guided trips matter.
