You can get a colectivo from San Martín and Pellegrini at 9.30am to the start of the trailhead (13k from town and up a dusty, gravel road). It’s 1k to Bosque Tallado and another 800 meters to Refugio Piltriquitron. Then it’s just over 3k to the summit. This 3k took us just under 2 hours ( we are fast walkers. It will take an average walker much longer). It is not an easy hike, but the view is well worth it. If you have walking poles .... take them ! If you don’t .... good luck, especially with the downhill.

The hike to the summit gets very steep in the last km, and the trail is very slippery because of the mud/gravel mixture. Go there with good hiking shoes and good physical condition. The view is breathtaking, and people with vertigo could feel uncomfortable given the cliffs and very steep sections (DO NOT FORGET to register at the refugio before climbing. DO NOT FORGET to go and tell the refugio manager when you are back from the summit, otherwise he will have to go up there to look for you...). The refugio is a wonderful place to get some excellent home-made food and beer. You can also sleep in a dorm for a reasonable price (around 300 pesos a night). The guy (Rodolpho if I remember well) who manages the refugio is very nice and you can have a chat with him about life in the mountains. He knows it all about the place and will be happy to inform you. The place has a great athmosphere, so do not miss the opportunity to stop there. Access: if you have a car, you can drive up to the "plataforma" 1 km under the Bosque Tallado. Be warned that the road to get there is in terrible condition and very steep. We have seen some guys with Renault Clio and similar 2WD drive up there, but we felt way safer in our 4WD. Have a wonderful hike!
