In the Maldives, it's impossible to remain estranged from the ocean's majesty. Travelers who can pry themselves away from the infinity pool gravitate toward the Indian Ocean, and its sea life plays a starring role in any Maldives vacation. Brilliant fish, gliding stingrays, placid turtles, and sleek sharks swim just offshore. Active travelers can snag a snorkel to peer beneath the surface, but the truly adventurous should book a diving excursion. Most resorts also offer sailing on a traditional Maldivian boat—for a dash of extra magic, book a sunset cruise or a dolphin-watching tour.
