St. John's heart is Virgin Islands National Park, a treasure that takes up a full two-thirds of St. John's 20 square mi (53 square km). The park helps keep the island's interior in its pristine and undisturbed state, but if you go at midday, you'll probably have to share your stretch of beach with others, particularly at Trunk Bay. The island is booming, and it can get a tad crowded at the ever-popular Trunk Bay Beach during the busy winter season. It's easy to escape from the fray, however: just head off on a hike or go early or late to the beach. The sun won't be as strong, and you may have that perfect crescent of white sand all to yourself.
