The largest barrier reef in the Western Hemisphere, Belize's 185-mile-long barrier reef is second only to Australia’s and a lot closer and cheaper for North American divers. Here you can experience more than 70 species of hard coral and 400 species of fish, plus three of the Caribbean's four rare coral atolls and one of the most coveted dive sites on earth—the Blue Hole.
Ambergris Cay, a narrow, 25-mile-long island located a 20-minute flight from Belize City, is the most popular base for exploring the reefs. Many hotels and dive shops on this laid-back island sell dive packages.
Popular local reef sites such as Cypress Garden, Victoria Cavern, Mayan Princess, and Tackle Box Canyon can be reached by a short boat ride. "Groupers, barracudas, sting and eagle rays, turtles, and nurse sharks are commonly seen here, as well as reef sharks, dolphins, and manta rays from time to time,”.
You can upgrade the night dive to a full-day excursion to the Blue Hole and two other sites in the Lighthouse Reef Atoll. More than 400 feet deep and 1,000 feet across, the Blue Hole is an ancient limestone cave whose ceiling collapsed, forming a perfectly circular reef. Its depth in comparison to the reef around it produces its color, causing it to look like a deep blue iris staring out of the paler blue Caribbean. You'll dive to a depth of 130 feet, where you can swim among the cavern's massive stalactites and limestone pillars and catch a glimpse of some of region's most fearsome fish: bull, reef, and hammerhead sharks.
