Exploring Bridgetown’s UNESCO World Heritage-listed colonial center is just the beginning of your Barbados adventure with Holland America Line. A number of Caribbean cruises call in the island’s capital for a chance to relax on its famous beaches, gawk at green monkeys, visit the world’s oldest rum distillery, and fill your Instagram feed on a Barbados photo expedition. Other Bridgetown shore tours take you underground at Harrison’s Caves and underwater on a submarine ride off Barbados’ coast.
