Snuba in Big Island

Snuba—a cross between scuba and snorkeling—is a great choice for non-scuba divers who want to go a step beyond snorkeling. You and an instructor dive off a raft attached to a 25-foot hose and regulator; you can dive as deep as 20 feet or so. This is a good way to explore reefs a bit deeper than you can get to by snorkeling. If you get frightened or need a rest, the raft is right there, ready to support you.

Snuba Big Island. Rendezvous with your instructor across from King Kamehameha's Kona Beach Hotel in Kailua-Kona for 30 minutes of instruction and a one-hour dive in Kailua Bay ($79 per person). Boat dives lasting three hours leave from Honakahou Harbor ($125 per person). You can also dive in Kealakekua Bay. The minimum age for snuba is eight, but kids four to seven can come along on the Snuba Doo program, which keeps them snorkeling safely on the surface. 808/326-7446. www.snubabigisland.com.
