The canyoning tour Matacanes starts in the town of Potrero Redondo in the middle of the Santiago sierra. It lasts for about 10 hours where you will find two rappel descents (27 and 15 meters), two underground rivers by which you will cross, 25 jumps to water (from 1-12 meters), slides, and many obstacles . Start walking a very rugged gap which is then converted to a path down to the waterfall Lagunillas with a rappel down 27 meters to have the first contact with the water. From this point enters the canyon to go to Las Adjuntas (includes abseiling course).
