It is the main attraction of the province, it is a heavenly place with a very fragile ecosystem, where you can appreciate the richness and humidity of the jungle in perfect balance. Traditionally the area has been inhabited by five communities (Siona, Secoya, Kichwas, Shuars and Cofanes) along the Aguarico River.
In addition, the Cuyabeno lagoons have common characteristics and features that distinguish among them are: Patacocha with abundance of patillos and cormorants, Caimancocha with an exceptional population of alligators, Charapacocha with peculiar turtles called charapas, Laguna Grande with pink and gray dolphin, the manatee and the paiche (considered one of the oldest in the Amazon R), the Laguna Canangueño considered by the Sionas as the most beautiful. Here you can navigate among the tree tops of a macrolobium forest, where different species of orchids grow and birds build their nests.
