Off the sandy peninsular of Placencia boasts some of the best and quietest dive sites in Belize. The main attraction is the 13 mile long lagoon, home to almost all creatures found on the outer reef, including manatee and dolphins. At the most northern point, due to the seasonal spawning of cubera snapper between April and June, Gladden Split sees an exciting amount of fish accumulate including hammerhead, bull sharks, whale sharks, dolphins and shoaling fish. Throughout the year you can expect to turtles, moray eels, spotted eagle rays, stingrays, large grouper, dolphin, nurse sharks and the usual species of tropical reef fish.
Laughing Bird Caye, part of the Belize Barrier Reef Reserve System World Heritage Site, is a submerged atoll. There is a system of patch reefs and coral ridges teeming with hard coral and sponges, plus dozens of reef species that feed on algae and each other. Keep an eye out for large barracuda feeding on the smaller reef fish.
