St. Regis Bahia Beach Resort, Puerto Rico
Between El Yunque National Forest and the Río Espíritu Santo, this luxurious, environmentally aware property, with 3 km (2 miles) of pristine private beach, is an oasis of calm that hums with local wildlife. The former coconut plantation occupies 483 acres and has an oceanfront golf course designed by Robert Trent Jones Jr. that weaves through mangroves. Spacious rooms are in low-rise, plantation-style buildings that highlight natural materials and feature numerous amenities; massive suites include butler service. Hike, bird-watch, run, or kayak through the property if you're feeling active. If not, score a cabana at the pristine pool, or laze in a chaise and order cocktails on the beach. The weary can indulge in treatments in the 10,000-square-foot Iridium Spa.
