Working with local indigenous communities, Teorumi is a great choice for anyone interested in native culture as well as wildlife. Tours can be tailored to fit your interests, though most feature bird-watching, fishing, medicinal-plant demonstrations and jungle hikes. Other activities include panning for gold and horseback riding. English and French are spoken. The office is on the main square.
Their nearby Shiripuno Lodge is often a base for activities.
Teorumi's owner is one of Ecuador's foremost authorities on snakes and their venom, and has helped create several antidotes.
