- Caverns: Located off the Poipu Beach resort area, this site consists of a series of lava tubes interconnected by a chain of archways. A constant parade of fish streams by (even shy lionfish are spotted lurking in crevices), brightly hued Hawaiian lobsters hide in the lava's tiny holes, and turtles swim past.
- Hanalei Beach: Divers love this area because it has an ancient sunken valley with post-erosional cliffs. Hanalei Bay indents the coast a full mile inland and runs 2 miles point to point, with coral reefs on either side and a patch of coral in the middle -- plus a sunken ship that belonged to a king, which means excellent diving.
- Oceanarium: Northwest of Hanalei Bay you'll find this kaleidoscopic marine world in a horseshoe-shaped cove. From the rare (long-handed spiny lobsters) to the more common (taape, conger eels, and nudibranchs), the resident population is one of the more diverse on the island. The topography, which features pinnacles, ridges, and archways, is covered with cup corals, black-coral trees, and nooks and crannies enough for a dozen dives.
- Haena Beach Park: In summer when the water calms down, this gold-sand beach becomes a giant aquarium, great for snorkeling amid clouds of tropical fish.
- Kee Beach: Where the road ends on the North Shore, you'll find a dandy little reddish-gold-sand beach almost too beautiful to be real. It borders a reef-protected cove at the foot of fluted volcanic cliffs. Swimming and snorkeling are safe inside the reef, where long-nosed butterfly fish flit about and schools of taape (blue stripe snapper) swarm over the coral.
