Blackbird Caye, Belize You’ll have to try really hard to do much better than this sublime 18-cabana spot on Turneffe Atoll, which is the closest resort to the Great Blue Hole and sits within 15 minutes’ boat ride of 70 more Belize dive sites. So do yourself a favor and book a three-, four- or seven-night package, which includes three underwater excursions a day.
