The Beni Biological Station (EBB) is a biosphere reserve located in the Beni Department of northeastern Bolivia. Established in 1982, the protected area covers approximately 1,350 square kilometers and was recognized by UNESCO in 1986. The region is an ecological mosaic of seasonally flooded savannas, wetlands, and gallery forests typical of the Llanos de Moxos. The EBB is an internationally significant research center focused on studying tropical ecosystems and protecting endangered species. Animals living here include the maned wolf, the giant anteater, and the rare blue-throated macaw. A unique feature of the reserve is the involvement of the local Chimane indigenous people in its management, linking nature conservation with cultural preservation. The area also serves to protect archaeological sites belonging to pre-Columbian hydraulic cultures. Despite its status, the reserve is threatened by cattle ranching and poaching.

📅

Best season

The best time to visit Beni Biological Station is the dry season from May to October, when the savannas are more accessible. During this time, waterfowl concentrate at remaining water sources and are easily observed.

Best time of day

River dolphins are most active early morning or late afternoon when they forage for food. Waterfowl also show the most activity during the cooler morning hours.

📜

Etiquette

Keep at least 50 meters distance from river dolphins to avoid disturbing them. Avoid motorboats near them, as the noise can stress the animals.

🎒

What to bring

Good magnification binoculars are essential for birdwatching and spotting dolphins. Sturdy footwear and insect repellent are important due to the humid savanna environment.

🧭

Getting there

Beni Biological Station is remote in the Bolivian Amazon basin, reachable only by flight to Rurrenabaque and then by boat. Organized tours are offered from Rurrenabaque.

What to expect

River dolphins are not always visible as they travel long distances. Patient observation from elevated viewpoints or boat trips increases your chances.
