Like most visitors to French Polynesia, I soon grab the ferry to Moorea, just 20km (12 miles) west of Tahiti. James Michener may have thought Bora Bora was the world's most beautiful island, but Moorea is my choice. In fact, it's so stunningly gorgeous that I have trouble keeping my eyes on the road here. Hollywood often uses stock shots of Moorea's jagged mountains, deep bays, and emerald lagoons to create a South Seas setting for movies that don't even take place in French Polynesia.

Geologists attribute Moorea's rugged, otherworldly beauty to a great volcano, the northern half of which either fell into the sea or was blown away in a cataclysmic explosion, leaving the heart-shaped island we see today. In other words, Moorea is only half of its old self. The remaining rim of the crater has eroded into the jagged peaks and spires that give the island its haunting, dinosaurlike profile. Cathedral-like Mount Mouaroa -- Moorea's trademark "Shark's Tooth" or "Bali Hai Mountain" -- shows up on innumerable postcards and on the 100CFP coin.

Mount Rotui stands alone in the center of the ancient crater, its black cliffs and stovepipe buttresses dropping dramatically into Cook's Bay and Opunohu Bay, two dark blue fingers that cut deep into Moorea's interior. These mountain-shrouded bays are certainly among the world's most photographed bodies of water.

Perched high up on the crater's wall, the Belvédère overlooks both bays, Mount Rotui, and the jagged old crater rim curving off to left and right. Do not miss the Belvédère, for it is one of the South Pacific's most awesome panoramas.

With traffic choking Tahiti, and Moorea only a 30-minute ferry ride away from Papeete, the island is already a bedroom community for its big sister. Still, it has maintained its Polynesian charm to a large extent. Its hotels and resorts are spread out enough so that you don't feel like you're in a tourist trap, and the locals don't feel inundated by us. They still have time to stop and talk with visitors.

Most of Moorea's 20,000 or so residents live on the coastal plain fringing the island, many of them in small settlements where lush valleys meet a lagoon enclosed by an offshore coral reef. This calm blue lagoon makes Moorea ideal for swimming, boating, snorkeling, and diving. Unlike the black sands of Tahiti, white beaches stretch for miles on Moorea.
