The most easterly of Belize’s three atolls, Lighthouse Reef lies 50 miles southeast of Belize City. The 30-mile-long, 8-mile-wide lagoon is the location of the Blue Hole , a dive spot that was made famous by Jacques Cousteau and that is a favorite destination of dive boats from Belize City , Ambergris Caye , and Caye Caulker . The best dive spots, however, are along the walls of Half Moon Caye  and Long Caye, where the diving rivals that of any in the world.
Think of the atoll as a large spatula with a short handle and a long blade. At the northern tip of the spatula blade, Sandbore Caye is home to a rusty lighthouse and a few fishing shacks. It is also the favorite anchorage of several of the dive boats that do overnight stops, including Reef Roamer II.
Big Northern Caye, across a narrow strait, has a landing strip that used to serve the closed resort here. There are long stretches of beach to walk, beautiful vistas, mangroves, and lagoons, home to snowy egrets and crocodiles.
Halfway down the spatula-shaped atoll, about where the blade meets the handle, lies the magnificent Blue Hole, a formation best appreciated from the air, but also impressive from the bridge of a boat.
At the elbow of the handle is Half Moon Caye, a historical natural monument and protected area with its lighthouse, bird sanctuary, shipwrecks, and incredible diving offshore. Finally, on the handle, we come upon Long Caye, a lonely outpost with a small dock, large palms, and glassy water.
