Aruba's capital sits just 15 miles off the Venezuelan coast, and it's one of the southern Caribbean's most popular cruise stops for good reason. Five berths across three air-conditioned terminals handle up to five ships at once, with water depths of 32 to 36 feet.

Cartagena de Indias is a Caribbean port city of about 1 million people on Colombia's northern coast, and one of the best-preserved colonial cities in the Americas.
