From the town of Luquillo, beachcomb along deserted shores to La Selva Beach, a surfing paradise in La Selva Nature Reserve. Officially known as the Northeast Ecological Corridor, this reserve protects 3,240 acres of freshwater marshes, coastal forests, sandy beaches and coral reefs. A refuge for over forty rare and threatened species, it is the most important nesting site in the Caribbean for the endangered Leatherback Turtle (Dermochelys coriacea), the largest turtle and one of the largest living reptiles on Earth. After a box lunch, continue to Seven Seas Beach, one of the island’s most beautiful. Its waters appear to have seven colors that shift in the changing light. Enjoy a swim or snorkel before returning to Yuquiyu.
