Desafio guides were great for both excursions. Rio Toro is highly recommended. And the rappeling was a great experience, even for someone with a fear of heights. The Canyoneering trip (rapelling) was strenuous as you had to do some hiking over rocky wet waterfalls between the rappels- but the guides were very helpful in making you as comfortable as possible traversing the terrain. There was also a mega amount of stairs at the end- but nobody rushes you.
