A Caribbean island is the perfect literal jumping-off point for a snorkeling or diving excursion, with waters just as welcoming as the islanders themselves. Lounge on smooth stretches of white, pink and black sandy beaches that spill into the coolest, bluest waters. But this archipelago made up of thousands of distinct islands offers something a little different to each traveler. From the lush natural greenery of Dominica to the lively and musical streets of Puerto Rico, there’s a slice of Caribbean heaven here, whatever your interests.
