Group of 9. Cool first thing in the morning and then bearable heat. Finishing at 32º. The tour of San Martín through the swamp is less oisterous and more fun. After the ascent of El Morro, we do not continue along the road to Navas, we take a much more entertaining detour to the right. Good route.

Group of 5. Cold at first, an hour later the fingers could move and the ears recovered their temperature. Very piste route without complications, the climb to the Morro was the most remarkable in terms of effort. Very sandy terrain and many sections, it already seems like summer.
