Lanai has Hawaii's best water clarity because it lacks major development, has low rainfall and runoff, and because its coast is washed clean daily by the sea current known as "The Way to Tahiti." But the strong sea currents pose a threat to swimmers, and there are few good surf breaks. Most of the aquatic adventures -- swimming, snorkeling, scuba diving -- are centered on the somewhat protected south shore, around Hulopoe Bay.
Body Boarding (Boogie Boarding), Bodysurfing & Board Surfing--When the surf's up on Lanai, it's a real treat. Under the right conditions, Hulopoe and Polihua are both great for catching waves. Boogie Boards ($10 a day) are available through Adventure Lanai Ecocentre (tel. 808/565-7737 or 808/565-7373; www.adventurelanai.com). The beach shack at Hulopoe Beach has complimentary Boogie Boards for hotel guests (Manele Bay and the Lodge at Koele) only.
