Bonaire is the “B” in the southern Caribbean’s ABC island trio — Aruba and Curacao are the other, more well-known sisters. This tiny island enjoys its rep as a diver's paradise and a place where visitors can truly relax. Don’t expect tons of bustling bars or clanging casinos at the Kralendijk port. Instead, get out and enjoy nature, from the thousands of flamingos at the Gotomeer saltwater lagoon to the gentle waters at Chachacha Beach.
