The world's largest coral reef eco-system actually consists of 3,000 separate reefs. The island of Moorea serves as the perfect base camp for snorkelers and scuba divers seeking to come face-to-face with the diversity of life that darts among the coral. Non-swimmers can enjoy the same parade of astounding creatures from the dry perch of a glass-bottomed boat. Formed when half of a monolithic volcano crumbled to the blue-green sea, Moorea is an achingly exquisite heart-shaped island that is simply paradise found.
