I do have the beta on about a dozen good runs in the Santa Domingo area. Look me up when you get down here. The best timing would be to hit Santa Domingo towards the end of your stay since that would be the best water level over there. Definitly check out the Qujos Valley as well. The paddling is increadable even if the after paddling adventures are more limited than in Tena. We hope to have a new play hole built infront of the Small World Lodge on the Quijos by mid December too.
