La Paseadora. For more than 20 years, Captain Frank Lopez has been sailing visitors from Naguabo's Malecón around Cayo Santiago aboard his boat, La Paseadora. Lopez, a charming, well-informed guide, gears the outings to the group, and over the course of three hours, you can motor around and watch the monkeys at Monkey Island—one of the world's oldest primate colonies. Plan to make some fishing and snorkeling stops in local waters using onboard gear. Playa Húcares dock, Rte. 3, Km 66.6, Naguabo, n/a Puerto Rico, 00718. 787/850–7881; 787/316–0441.
