China Walls / Portlock Wall Verified
Hawaii - Oahu · 9–17 m
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.

Amber's Arches Verified
Hawaii · 12–24 m
Amber's Arches is a Kauai south-shore boat dive with a reef plateau, drop-off, arch/ledge features, holes, and undercut structure. It is attractive for eels, lobsters, dark-loving fish, reef sharks, and occasional rare finds such as longnose hawkfish in black coral. Treat the arch and hole features as swim-throughs, not caves for untrained penetration.

Farnsworth Bank
California · 16.8–39.6 m
Open-ocean seamount about 1.5-2 miles off the backside (southwest) of Catalina Island, with pinnacles rising from 200+ ft to peaks around 55-60 ft. It is famous for dense stands of protected California purple hydrocoral covering the walls, with most diving in the 90-110 ft range. Exposed position means it is only diveable in calm seas, and currents can be strong; the site is protected within the Farnsworth Offshore State Marine Conservation Area.

Herring Cove Beach
Massachusetts · 3–6.1 m
Herring Cove Beach in Provincetown, part of the Cape Cod National Seashore, is a calm west-facing shore dive over a gently sloping sand bottom bordered by rocky stretches and patches of eelgrass, with depths of roughly 10-20 ft close to shore. It is best known for snorkeling and easy diving on bottom dwellers like crabs, lobsters, flounder, and sea robins, and locals rate it as one of the best night dive spots in the area. Strong tidal currents run offshore toward Race Point, so divers should stay within the cove. Visibility of 30-40 ft is possible around slack high tide.

Enenue Verified
Hawaii · 6–18 m
Enenue is an inner/eastern Molokini site with a gentle reef slope and abundant butterflyfish in the shallows. It supports snorkeling, freediving, SNUBA, and scuba when boat conditions are calm. Deeper portions toward the wall can add sharks/eels/rays and a more advanced feel.
