🚤 Mona Passage

The Mona Passage is a strait that separates the islands of Hispaniola and Puerto Rico in the Greater Antilles of the Caribbean region. Along with the Windward Passage between Hispaniola and Cuba, the approximately 80 miles (130 km) wide Mona Passage connects the North Atlantic Ocean to the Caribbean Sea, operating as an important shipping route between the North Atlantic and the Panama Canal. The passage is fraught with variable tidal currents created by the islands on either side of it, and by sand banks that extend out from both coasts.
