Hacienda La Esperanza


Venture knee-deep into wetlands or walk across grasslands that disappear in the horizon. Hike your way through mangroves until reaching an estuary with crystal-clear waters or climb to the top of a karst hill and explore the remains of a 19th century sugar hacienda that flourished with thanks to the Río Grande de Mantí.

There is so much to see and do for every skill level at Hacienda La Esperanza Nature Reserve in Manatí, the biggest of its type in the northwest area of Puerto Rico.

The visitor center at La Esperanza is part of a carefully rehabilitated historical site that conserves the only sugar mill steam engine of its kind in existence, completely restored so you can see it in operation.

The old manor house at the site serves today as Para la Naturaleza’s regional headquarters, complete with its own scientific lab. Citizen Science research about birds, crustaceans, bats, coasts and archaeology are still based here. You can always take part of Citizen Science events or let a history and nature expert guide you through the ecosystems of the reserve.
