A green jewel in the ocean four and a half kilometers off the Belize coast with all the ingredients for perfect island happiness: powdery white sand, coconut palms shading your chaise lounge, warm crystal-clear water flowing in countless emerald hues. Best of all, you share this perfect Caribbean islet with no more than 16 guests. Six elegant and light-filled wood villas are scattered about the island; one more was built on stilts over the water. Waiting to be explored is an underwater world of incomparable diversity. Just twenty minutes away by boat is the second-largest reef—after the Great Barrier Reef—in all the world’s oceans.
