This is a kayak/boat dive from the harbor because entry/egress to the cove over the rocks is hazardous. Snorkelers are less encumbered and can make it over the rocks. It's an uncomplicated kayak or inflatable launch from the beach, since the surf is little more than a ripple. Powerboats are lowered to the harbor by 15 & 25-ton cranes for a small fee. Viz in Nellie's Cove and adjacent Tichenor's cove was poor (5 to 8 ft) on 4 dives, 2 occasions. Noted a good population of rockfish, moon snails, crab. I anchored my dive kayak in 32-35 ft depth. Other divers advise that conditions are occasionally very good, but my timing was poor on a subsequent summer visit also. Prevailing wind increased in the afternoon. Return to the harbor around the breakwater with the kayak was uncomplicated by surf. Vehicles (4WD with off-road tires recommended) were permitted on the beach to facilitate transport of boat and gear, but the resolute diver can carry the gear from the parking area. Showers & restrooms available. Food concession nearby. Time constraints did not permit night dives. Affordable lodging available at Castaways and Sea Crest Motel. Diving fell short of expectations, but the kayaking was fun and the scenery was a "Kodak moment" that justified the trip for me.
