This beautiful reserve is a unique flooded rainforest covering 6034 sq km around Río Cuyabeno. Seasonally inundated with water, the flooded forest provides a home to diverse aquatic species and birdlife – not to mention pink river dolphins, manatees, caiman and anacondas, several monkey and cat species, tapirs, peccaries and agoutis. Macrolobium and ceiba treetops thrust out from the underwater forest, creating a stunning visual effect. The blackwater rivers, rich in tannins from decomposing foliage, form a maze of waterways that feed the lagoons.
Due to its remoteness, and to protect the communities within it, travelers should only visit the reserve on guided tours – which are significantly cheaper, and often yield richer wildlife sightings, than in Parque Nacional Yasuní.
