Advanced Open Water - advanced conditions (currents/depth); dive within your training.
Snorkelling
Not a snorkel site - no
Safety notes
Steep drop-offs beyond recreational limits, potential currents/upwelling, long surface swims to reach the canyon, boat/kayak/paddleboard traffic near Scripps pier; site sits inside a no-take ecological reserve - no collecting or disturbing marine life or rocks. Night diving is popular but adds hazard for less experienced divers
Permits & fees
No permit or entry fee - public shore access; the ecological reserve is a total no-take zone so a CA fishing license does not authorize any take here. Dive flag required by California law when diving from shore
Permits and operators change - confirm before booking.
