Catalina Two Harbors

Long Beach · California · United States

Two Harbors occupies the narrow isthmus at Catalina Island's western end, twenty-six miles offshore from Los Angeles. While Avalon draws weekend tourists, the west end remains wild. The kelp forests here are among the healthiest in Southern California, and the marine life has the size and confidence that comes from decades of marine reserve protection. The dive boat anchored in Catalina Harbour, and we descended through the kelp canopy like entering a cathedral, golden-brown fronds reaching twenty metres from the rocky bottom to the surface, sunlight filtering through in shifting columns. A giant black sea bass materialised from between the kelp stipes at fifteen metres. The animal was enormous, easily two metres, its dark body blocking the light as it cruised past at arm's length. It turned its head to regard me with one large eye, showing no concern, then continued with slow tail beats. I saw three more during the dive, including two at the reef edge that appeared to be a mating pair. Garibaldi were everywhere, California's state marine fish, their brilliant orange bodies the most vivid colour in the kelp forest. Males defended nest territories with aggressive displays. California sheephead worked the reef surface, their heavy teeth cracking sea urchins with audible crunches. The second dive followed a wall on the island's exposed western face, dropping from five metres to thirty over rocky substrate covered in purple gorgonian fans. Bat rays glided along the wall edge, their diamond shapes distinctive against the blue beyond. A horn shark rested in a crevice at twenty metres. Two Harbors demonstrates what California's kelp forest ecosystems look like when properly protected. The giant black sea bass recovery is a conservation success story visible on every dive, and this end of Catalina delivers diving that genuinely surprises visitors who think the best diving requires tropical water.
