This lake is 5km east of Boca de Guamá via the Canal de la Laguna, accessible only by boat. On the far (east) side of the 92-sq-km body of water is a tourist resort named Villa Guamá, built to resemble a Taíno village, on a dozen small islands.
A sculpture park next to the mock village has 32 life-size figures of Taíno villagers in a variety of idealized poses. The lake is called 'Treasure Lake' due to a legend about some treasure the Taíno supposedly threw into the water just prior to the Spanish conquest (not dissimilar to South American El Dorado legends). The lake is stocked with largemouth bass, so fishers frequently convene.
