Oriente is the Ecuadorian term for the huge region with Amazon tributaries. Ours was the Napo River, and the entire navigation is by motorized canoe or tug and barge. It was good to go to Sacha, which is a couple hours from Coca, but in an area almost completely virgin forest. I think there was not a car within 300 square miles. Every move was by canoe or hike or climb - and the Sacha guias were more than willing to haul all the junk we carry.
