From Ceiba, a ten-minute flight takes guests to picturesque Culebra Island. Like Vieques, its larger sister island to the south, Culebra is blessed with sparkling beaches. From the dock at Ensenada Honda, take a water taxi to one of two islets in the Culebra National Wildlife Refuge: either Culebrita or Luis Peña. If Culebrita, hike up the hill to the historic lighthouse and across the island to the fantastic crescent beach on the north shore. Even though Luis Peña doesn’t have a lighthouse, it is equally delightful. After snorkeling, swimming and a picnic, return to port. Spend the rest of the day swimming and sunning at renowned Flamenco Beach until your flight back. If you don’t mind a boatload of people, take a snorkel and beach cruise from Puerto Rico’s east coast. As day ends, return to the mainland and Yuquiyú.
