Melchor Island, named after one of the biblical Magi, is the middle jewel of the Tres Reyes archipelago. Unlike its sandy neighbor Gaspar, Melchor is characterized by dramatic, sheer limestone cliffs that plunge vertically into incredibly deep, sapphire-blue waters. The island is completely uninhabited and cloaked in dense tropical foliage. The deep waters surrounding the island drop off precipitously, creating strong currents that attract large pelagic fish. Hidden beneath the rugged cliffs are small sea caves and grottos that can only be explored by experienced divers during favorable tidal conditions. **Traveler Logistics:** Melchor is typically included as a sightseeing stop during a standard Tres Reyes island-hopping tour. Boats usually circle the island to allow visitors to photograph the striking geological formations, as there are no accessible beaches for docking.
