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. 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.
