The Otin canyon provides one of most challenging descents in the whole of the Sierra de Guara in terms of physical exertion and technique.  In the form of a steep staircase, the canyon is often dry but can be subject to torrential water flow after periods of rain.  It offers 16 steep drops for abseiling, some of which require “mid-air” descent without touching the canyon walls. Otín is a great choice after rainy spells, although as with all canyons, it is necessary to evaluate the risk in the case of sudden water rises after heavy storms.  When the canyon is dry, some of the water pools dry out to create deep traps with smooth sides; they are difficult to get out of and usually require a good knowledge and sound experience of rock climbing.

It is an essential descent for lovers of canyoning but should only be undertaken buy professionals and those people who are well prepared both in terms of physical condition and technical ability.  The use of a professional guide is highly recommended.

It is necessary to check the access restrictions due to environmental issues (express authorization is needed for the decrease between March 1 and June 30, inclusive).

Technical information

Approach: 2 hours. From Rodellar, take the well marked path down to the river bed, and once there follow the river upstream for around 45 minutes until reaching a fork to the left signed as Otín and Mascún.  After an arduous climb and before arriving at the abandoned village of Otín, the canyon can be seen to the right.  Two large oak trees indicate the start of a path to the right, which takes you down to the water. Nearest village: Rodellar

Descent: 4 - 5 hours    KM: 500m

Retour: 1h:30min (return via the last stretch of the Mascún canyon (avoidable if necessary) until arriving at Beso.  This is a famous formation of two large rocks at the end of the Mascún canyon that appear to be “kissing”.

Escape routes: There are various places to shelter out of the water but no decent escape route until the final rappel; the path that connects with Mascún.
