Huge canyon with well equiped single pitch sport routes up to 35 metres. Some multipitch sport and trad is also available. The guidebook is available in Buenos Aires and Esquel. There is an old 2012 edition at the campsite and if you are lucky they will have the new guide in the shop but it's not too difficult to find someone at the crag with a topo or who can point you at the classics.
Camping is around 100 pesos per person per night, with hot showers 7pm to 10pm every second day (expect queues!) and charging points at the same time every night (Although you wont get any signal). There is a small shop with wine, beers, bread, cheese, eggs and other fruit / snacks but it is recommended to come prepared with plenty of food for your stay. It's a long drive to civilisation. Take all litter with you when you depart and drop in bins in the nearest town.
