Pacuare Outdoor Center has been running the river since 2003, with one- and two-day Pacuare trips, canyoning and ziplines alongside, and a lot of student and group travel — which means they are organised about logistics and safety briefings in a way smaller outfits sometimes are not.
The two-day version, sleeping at a camp on the riverbank between two days of rapids, is the better trip if you have the time.
