Ecuador is any whitewater rafter's paradise. This is because of the jungles and rivers accessible in a small area, making travel time shorter than what you will naturally have when you decide to raft somewhere else. Furthermore, the rivers in Ecuador vary in difficulty. This means that a beginner and an expert can surely find a suitable river to raft in.
Some of the most popular Ecuadorian rivers are Rio Napo, Rio Misahualli, Rio Blanco and Rio Toachi. Read more about them here in Spanish Abroad.
