See Humpback Whales
Each winter, a seamount off the Dominican Republic hosts a vast gathering of Atlantic humpback whales. The cetaceans, some up to 50 feet long and weighing 50 tons, use the bank as their birthing, nursery and mating grounds. Getting there requires a long boat ride and living aboard for a week, but the reward is no less than the greatest animal encounter available anywhere: meeting the most demonstrative of the great whales in its own element. Humpback season runs from the end of January until April.
