Portlock/China Walls is a lava wall and cave/nook dive along Oahu's southeast shore. The underwater route follows the cliff wall past caves, arches, and mini-canyon features where turtles and whitetip reef sharks may rest. It is a rewarding dive only in very calm conditions and is safer by boat for many divers.
Hawaii - Oahu · 0.1–3 m
Boat-access sandbar and shallow reef-edge snorkel area in Kaneohe Bay. Water over the sandbar can range from ankle-deep to waist-deep with tide, while nearby reef patches support fish, coral, and occasional turtles. It should be represented as snorkeling/freediving/ocean recreation, not scuba.

West Oahu lava-tube/cavern and reef system near Makaha/Kepuhi Point. The site has open-ended swim-throughs, skylights, collapsed tube sections, and frequent turtles, puffers, lobsters, and whitetip reef sharks. Boat access is preferred for scuba; confident snorkelers/freedivers may use calm windows but should avoid overhead areas beyond training.
Hawaii - Oahu · 1.5–14 m
Three Tables is the southern Pūpūkea Beach Park/MLCD reef site, named for flat reef tables visible at low tide.
