Baja California Norte's diving is anchored entirely in the Coronado Islands, a cluster of sites where kelp forest, reef, wall, pinnacle and wreck terrain sit side by side. Harbor Seal and California Sea Lion are encountered across nearly every site, while Garibaldi, Scorpionfish, Sea Star and the vivid Spanish Shawl nudibranch colour the reefs. Conditions range from sheltered beginner dives at South Coronado Island and Kennedy Cove to demanding drift dives and deep walls at El Reef, Roca el Aguila and Campo 7 sección 1. All sites require boat access.
