You’re guaranteed to see all manner of critters at AmaZOOnico , a well-known animal rehabilitation center. The center is located on the grounds of Selva Viva, a 1500-hectare reserve of primary forest on Río Arajuno, a narrow tributary of the Napo about 3km east of Ahuano. A Swiss-Kichwa couple founded the center in 1995 to care for confiscated or displaced rainforest animals, from toucans and capybaras to monkeys and boa constrictors.
