Cuyabeno
A reserve of blackwater lagoons. Canoes, monkeys, caimans, and, with luck, river dolphins. Trips are a few nights. The road in is through Lago Agrio, in Sucumbíos. The US advisory says to reconsider travel to that province. The UK says Lago Agrio is inside the 20-kilometer border zone where it advises against all but essential travel, and it tells people going to Cuyabeno to use a reputable guide, move in daylight, and keep a way to communicate.
