Southwest Caye is a privately-owned island along the eastern portion of the Belize Barrier Reef, located 36 miles due east of Dangriga. The island is one of Belize's best diving spots, noted for its steep shoreline cliffs at heights of 130 and 350 feet that make for excellent unique diving platforms for experienced divers to see sea turtles, eagle rays, and a wide variety of corals and sponges. Snorkeling, SUP paddleboarding, kayaking, and saltwater fishing are also popular activities on the island, which is populated by tarpon, marlin, sailfish, and bonefish in its surrounding waters. The Isla Marisol private resort on the island offers 12 rental cabins and two large guest houses.
