Undeniably one of the most photographed beaches in the Caribbean, if not the world, Trunk Bay sits in the northwestern corner of the Virgin Islands National Park (it was donated to the park service by Laurence S. Rockefeller more than 50 years ago). Calm, clear water, and a 225-yard-long underwater trail for snorkeling are big draws, as are hiking trails up and into the surrounding greenery, filled with the ruins of historic sugar cane plantations.
