Hacienda La Esperanza is the carefully rehabilitated historic site of what was one of the most prosperous sugar plantations in Puerto Rico during the 19th century. The hacienda, located in a 2,150-acre nature reserve, is also home to a sugar mill and its unique 1861 West Point Foundry steam engine. The site's old manor house serves today as Para la Naturaleza’s regional headquarters and is complete with its own scientific lab.

Hacienda La Esperanza offers guided tours year round, as well as workshops, bird watching, volunteer activities, and seasonal events. Guided tours include venturing knee deep into wetlands, hiking through mangroves to reach an estuary with crystal clear waters, or climbing to the top of a karst hill (a topography that features sinkholes, caves, and underground streams) and exploring the remains of a 19th-century sugar hacienda that flourished, thanks to the Río Grande de Manatí.

Para la Naturaleza is a nonprofit unit of the Conservation Trust of Puerto Rico. It aims to integrate society at large into the conservation of natural ecosystems, in order to increase the amount of protected lands in Puerto Rico.
