Dorado Beach, a Ritz-Carlton Reserve, Puerto Rico

Come winter, some people would rather chill by a pool than catch a chill. For those in need of a few extra rays this season, here are seven standouts.

Dorado Beach, a Ritz-Carlton Reserve in Puerto Rico, maintains the minimalist barefoot elegance and sensitivity to the natural environment that were dear to the property’s founder, Laurance Rockefeller, who built the sanctuary in the 1950s. Re-opened by Ritz-Carlton last December after a comprehensive renovation and redesign, the resort sits on 1,400 acres of the former Rockefeller estate, with 100 guestrooms and 14 one-bedroom suites on the beach designed to immerse you in the coastal landscape with uninterrupted views. Making the most of the retreat’s lush surroundings, the property’s Spa Botánico occupies a five-acre haven with warm and cool pools, waterfall showers, glass-walled treatment pavilions, and open-air treehouse platforms.
