In 1979 the Cuyabeno Nature Reserve was founded between the rivers Aguarico and San Miguel, which is in the province of Sucumbios. The spectacular trips into Cuyabeno introduce the visitor to the complex system of tropical lagoons, swamps and flooded areas inhabited by the Siona Indian Community. Cuyabeno's abundant aquatic and land habitats are home to fresh water dolphins and turtles, anacondas, crocodiles, monkeys, ocelots, sloth and birds such as hoatzins, arras and kingfishers. A huge range of vegetation flourishes in this tropical rainforest: plants such as palms, bromeliads, ceibos, helicons, macrolobium, wild roses, orchids are frequently seen. This once-in-a-lifetime trip will definitely be a memorable experience for everyone who is fortunate enough to participate.
