Why dive here
Underwater Arch is a cave dive in California, United States. Water ranges 14-21°C, warmest July, August, September.
The Underwater Arch in California offers a unique experience for divers comfortable with overhead environments. We've found the rock formations here create some interesting swim-throughs and small caverns to explore. Visibility can be a factor, so we'd suggest picking a calm day for the best views of the resident rockfish and anemones clinging to the walls. It’s a good spot for divers looking for something a bit different from a typical reef dive.
Safety Notes
Overhead environment - never enter without proper cave/cavern training, redundant equipment, and a guideline.
