A nearby underground river feeds water to the brilliantly colored ponds known as Los Tres Ojos, which are accessible on foot or by boat. Travelers can explore the blue, green, and yellow waters that are rich with indigenous wildlife and that were once a source of survival for the first inhabitants of Hispaniola. Take a guided tour of the park to learn more about its history and natural features. These tours are often paired with a visit to the Columbus Lighthouse (Faro a Colon). Many sightseeing tours or day trips from Punta Cana also include a stop at the national park, along with other notable attractions like Calle de las Damas, Alzacar de Colon, and the Zona Colonial.
