Dive Site Characteristics
Dive Site Overview
Long Point, formally recognized as a State Marine Reserve (SMR), stretches across approximately two miles of shoreline midway between Avalon and Two Harbors on Santa Catalina Island. This protected status means all marine life, geological, and cultural resources within its boundaries are conserved.
Divers exploring this area will discover a consistently varied underwater landscape. It transitions from nearshore cobblestone areas to extensive rocky reefs that cascade down to recreational depths of around 30 m (100 ft). These reefs support diverse habitats, including vibrant kelp forests that sway with the currents and expansive sandy seafloors where various bottom-dwelling species reside.
Several boat-in campgrounds along the SMR's coastline, such as Goat Harbor and Italian Gardens, are popular starting points for dives, with some offering suitable anchoring spots in sand. The marine protected area also serves as a crucial spawning aggregation site for critically endangered giant sea bass during the late summer months, a significant ecological event.
Its designation as one of the most sheltered portions of the eastern Channel Islands significantly contributes to its appeal for both novice and intermediate divers seeking a reliable underwater experience.
