Tourists visiting Tanzania usually spend a few days on safari, spotting lions and zebras from their 4x4 vehicles. But clever tourists go on to experience an equally thrilling marine safari off the coast of Pemba Island. Among the island's several luxury resorts is Fundu Lagoon, a boutique beach hotel founded by British fashion and film designer Ellis Flyte. The property has its own diving facility, called Dive 710. The shallow coral lagoons, warm clear water, and unique locations like the Emerald Reef—an undersea garden of green-hued corals—make this region one of the best dive sites in the world. Divers off Pemba can expect to see fish of every color as well as sea turtles and rays.
