An eight-acre gumdrop of an island has been turned into the Royal Davui Island Resort by the Southwicks, a fifth-generation Fijian family who also operate a commercial fishing fleet in the area—hence, the sashimi of yellowfin tuna on the dinner menu. The resort has 16 mahogany vales, or villas, clinging to the cliffs above a marine sanctuary and a shallow reef that ripples turquoise and silver at dusk. Meals are served in a tree house built around a giant banyan. Tropical orchids and bamboo shade steep paths that are perfect for hiking. And don’t be afraid of a swim in the reef-protected waters of the Beqa Lagoon: the staff at the resort delights in telling guests about the myth of Masilaca, a god who is said to have taught the local Sawau tribe how to dance across hot coals without getting burned and who protects islanders—and visitors—from sharks.
