Mona Passage, Maritime strait between Puerto Rico and Dominican Republic, Caribbean Sea.
The Mona Passage is a maritime channel between Puerto Rico and the Dominican Republic, connecting the Atlantic Ocean with the Caribbean Sea. The waterway extends roughly 80 kilometers across deep waters that reach depths of approximately 4000 meters.
The passage was first navigated by Christopher Columbus in 1493 during his Caribbean exploration, followed by Juan Ponce de León in 1508. These early expeditions established it as a known route for European seafarers exploring the region.
The waterway serves as a key shipping route for vessels traveling between the Atlantic Ocean and the Panama Canal, linking regions and enabling trade between North and South America.
Ships must plan their navigation carefully due to strong currents, variable tidal patterns, and frequent weather changes. These rough conditions require experienced captains and constant monitoring when crossing the passage.
Three islands sit within the waters: Mona, Monito, and Desecheo, with the centrally located Mona Island distinguished by limestone cliffs rising about 60 meters high. These islands serve as important wildlife habitats and shelter rare ecosystems in the region.
