The island's famed offshore region, Silver Bank, welcomes humpback whales from December to April, when the giant mammals visit to calve. Divers will enjoy the location, as well as other wonderful sites off the destination's coast. Indeed, each region has its signature dives, where adventurers will encounter vibrant, fishy reefs and light-beam-filled caves. The island's brag-worthy list of natural and artificial wrecks will also interest divers. Some date back to the 16th century, courtesy of the first European to ever set foot in the Americas. Others come from the modern era. All in all, warm water and generally good visibility make the Dominican Republic a year-round destination for divers of every level.
