Costa Rica isn't known for coral reefs—it has very few, and small ones at that—but it contends with the world's best diving sites for its abundance of big fish. Most dive sites are on the Pacific coast, where you might have a close encounter with manta rays, giant groupers, and whale sharks; the Caribbean coast has relatively few sites, with a single coral reef off Gandoca-Manzanillo Wildlife Refuge. Diving Safaris travels to more than 20 dive sites off the coast of the Nicoya Peninsula. In Manuel Antonio, Oceans Unlimited offers trips to local sites and, if you can stand the two-hour journey, to what many say is the country's best dive site, Caño Island. Experienced divers go even farther afield to Cocos Island, which is actually a northern extension of the Galápagos chain: Two days aboard the Okeanos Aggressor is rewarded with the chance to dive amid huge schools of hammerheads.—Christopher P. Baker
