Heading south along the east coast, you eventually lose the cars, condos and tourists and enter a rural, slower-paced and infinitely more appealing part of Puerto Rico. The main towns here, Naguabo and Humacao, hold little interest for most visitors and once again, it’s the coast that provides the real allure. Highlights include the boat trip to Monkey Island (Cayo Santiago), some exceptional seafood restaurants at Playa Naguabo and Punta Santiago and the beaches and staggering vistas of PR-901, one of the most scenic roads on the island. Along the way, nature lovers should check out the thoroughbred Paso Fino horses at Palmas del Mar.
