Mona Island is an uninhabited island in the Mona Passage, run as a nature reserve by Puerto Rico's natural resources department (DRNA). Diving here is open-ocean: visibility runs 100–150 ft, and divers can encounter sharks, sea turtles and largely untouched coral. February through April is the best window for diving because the crossing is calmest.
Reaching the island means going by private boat or on a licensed trip from Cabo Rojo. Landing and camping both require a DRNA permit, and camping is allowed only from May to November.
