Deep in the Indian Ocean, the Maldives archipelago includes over 1,100 coral islands spread over a 35,000-square-mile area. Defined by a double chain of 26 atolls, its waters boast a huge variety of sea life and marine ecosystems. From Aug. 27–Sept. 3 and from Sept. 10–17, Four Seasons Resort Maldives offers a way to marvel up close as part of the Four Seasons Explorer’s Manta Trust Expeditions. The route for each expedition wends through the Baa and Ari Atolls, following the feeding path of manta rays and whale sharks.

Each all-inclusive cruise aboard the 128-foot luxury Four Seasons Explorer yacht is escorted by manta expert Guy Stevens, and organized in conjunction with The Manta Trust. No diving skills are necessary — viewings of manta rays and whale sharks are possible from on board the ship, as both species feed at the surface of the sea. Additional activities include participating in data collection as an honorary researcher, snorkeling and visiting isolated craft villages. As part of the experience, relax with a sandbank barbecue on a deserted isle, or schedule a castaway beach massage beside the sea.
