Saint John, US Virgin Islands
Why now: The rundown facilities at Saint John's Virgin Islands National Park will get a major revamp in 2017, most notably in Cinnamon Bay, where new dining options and eco-tents will liven up the park's only official lodgings. The island is also in the midst of a major conservation battle to prevent two large marina projects from mucking up the ecologically sensitive Coral Bay Harbor.
What to see: Rent a kayak or SUP at Cinnamon Bay's water sports facility to explore the coast. Then snorkel at nearby Waterlemon Cay, hike the Reef Bay Trail to Taíno petroglyphs, and finish the day with a Cruzan rum and coke on Gibney Beach.
