Cancún (Mexico's Yucatán Peninsula) and the Bahamas (Atlantic archipelago) are separated by the Florida Straits. The closest approach is between Cancún and Bimini, the westernmost Bahamian island chain—approximately 105 miles (169 km) apart.
Direct travel options are limited:
Cancún sits at 21.16°N, 86.85°W; Bimini at 25.73°N, 79.27°W. The Gulf Stream flows northward between them. Cuba lies 130 miles south of Cancún; Key West is 90 miles north of Bimini.
Travelers should verify visa requirements (Mexican and Bahamian regulations differ) and marine conditions—this crossing traverses open ocean with limited rescue infrastructure.
