Lagoa de Jacarepiá is a freshwater lagoon located in the Vilatur district of Saquarema, in the Região dos Lagos area of Rio de Janeiro state. The lagoon sits within the Reserva Ecológica Estadual de Jacarepiá, a state-protected ecological reserve established to preserve its natural ecosystems. The address is commonly referenced as Vilatur, Saquarema – RJ, 28990-000.

Access to the lagoon is typically via the Estrada dos Cajueiros, and most visitors arrive by car. GPS navigation is recommended for finding the precise put-in location. The calm, freshwater conditions make it a relatively approachable paddling environment, though the lagoon has been experiencing a drying trend, which paddlers should factor into trip planning — water levels may be lower than expected depending on the season.

As a protected ecological reserve, the surrounding landscape retains natural character, and the area is known for its scenic qualities, particularly at sunset. The calm water is a defining characteristic of the paddling experience here. Given its status as a state ecological reserve, paddlers should be aware that environmental regulations are likely in effect; respecting the natural environment and adhering to leave-no-trace principles is strongly advised.

Facilities and infrastructure at the lagoon are limited. There are no dining options nearby, so paddlers should bring their own food and water. The area lacks developed amenities such as lighting or maintained recreational infrastructure, so paddlers should plan accordingly and not expect formal launch facilities or support services on site.

The lagoon holds ecological significance as one of the more important water bodies in the Região dos Lagos, both for its biodiversity and its landscape value. Its freshwater character and protected status suggest a relatively undisturbed natural environment, though the drying of the lagoon is a concern worth monitoring before planning a visit.
