Located in the heart of the lush Tambopata National Reserve, Lake Sandoval is one of the most fascinating natural destinations in southeastern Peru.

A Close Encounter with Wildlife -Giant Otters in Tambopata

Giant otters, locally known as “river wolves,” can reach up to two meters in length and live in close-knit family groups. This social behavior makes them a captivating species for visitors, as they are often seen playing, fishing together, or communicating with unique vocalizations.

Unlike many other Amazonian animals, the otters of Lake Sandoval are relatively easy to spot. While their presence can’t be guaranteed, the chances of seeing them during a guided tour are quite high—especially in the early morning or at dusk, when they are most active.

Conservation and Responsible Tourism -Giant Otters in Tambopata

Observing giant otters in their natural habitat is not only an unforgettable experience but also an opportunity to reflect on the importance of conserving Amazonian ecosystems. The pressures of deforestation, illegal mining, and poaching have pushed this species to the brink of endangerment. That’s why sustainable tourism in protected areas like Tambopata plays a key role in their protection.

By visiting Lake Sandoval with certified tour operators, you support the local economy and ensure a respectful experience with the local flora and fauna. Local guides are trained to minimize human impact and maximize responsible wildlife viewing opportunities.

Access: Reachable by boat along the Madre de Dios River from Puerto Maldonado, followed by a 3 km (approx. 2 miles) hike to the lake.
