The site has good facilities and easy entry (beware of boat traffic since Kewalo Marina is co-located) into the boat channel. High surf can make entry and the long surface swim difficult and several dive operations use this as a boat dive especially at night which adds obvious hazards. Night diving is a hit and miss sometimes there are things to see others nothing special shows up. Average depth is about 30-40ft. The long pipe which ends a few hundred feet offshore provides occasional cover for many fish and a few octopus. There are several interesting reefs East of the pipe with some turtles (Horseshoe Reef) and another one a short distance to the West. Parking is fairly close as long as you get there early. Visibility gets better as you move away from the harbor unless heavy surf and rain stirs up the bottom.
