What was the first sea route to the West Indies Marco Polo?

Marco Polo did not discover a sea route to the West Indies; he traveled primarily overland along the Silk Road to Asia in the 13th century. The first significant European sea route to the West Indies was established later, primarily by Christopher Columbus in 1492 when he sailed west across the Atlantic Ocean. Columbus's voyages ultimately led to the European discovery of the Caribbean islands, which were later referred to as the West Indies.
