The Loreto Road on the east slope of the Andes runs along the baes of the 13,200 ft Sumaco Volcano in Napo Province of eastern Ecuador and connects the town of Coca (also called "Puerto Francisco de Orellana) on the Napo River with the Baeza-Tena Road and ultimately Quito. It's about a half-day drive from Coca to Quito along this road.
