Ponce de Leon never did find the Fountain of Youth, but he did find stumble upon this lovely island, which had to be a close second. Just move to the rhythm of the ever-present salsa beat and you’ll be in the spirit in no time (secret – it’s all in the hips). Old Town San Juan is still partially enclosed by the original fortress walls dating back to the early 1500s. Attractively restored buildings with filigree cast iron balconies line its narrow cobbled streets, and cafés in shaded squares provide an ideal spot to linger. Outside the city the island offers an appealing array of golf courses, rainforests, and beaches galore.
