Crescent Bay
Popular Laguna Beach shore dive with sandy access and rocky reef.
A busy North Laguna cove where a sandy entry leads to rocky reef and an outer reef farther out.
About Crescent Bay
Crescent Bay is a popular Laguna Beach shore dive with a sandy cove entry, Circle Way stairs, and a paved ramp near Cliff Drive. Seal Rock sits offshore, and the site unfolds from a shallow inner cove to a rocky outer reef farther out. It can be rewarding on calm windows, but surf, rip currents, and surge make the beach entry demanding when swell is up.

Local Intel For Crescent Bay
Community notes to help plan your visit.
Scuba Diving
Scuba divers can work the inner sandy cove on easier days, then push out toward Seal Rock and Dead Man's Reef only when surf and experience levels allow.
Freediving
Freediving is only practical on very calm days in the shallow inner cove. Surf, rip currents, and the longer swim to the outer reef make it a poor choice when swell is active.
Snorkeling
Snorkeling is only practical close to shore on calm days. Once surf and surge build, the site is better left to scuba divers.
