A nice climb from the El Burguillo reservoir. The first part is asphalt in very good condition (as of November 1, 2025), and the second part is a dirt track, also in very good condition. It's a demanding climb; the asphalt section offers some flatter sections, but the dirt track is practically a continuous gradient of around 10%.

Casillas is a municipality in the province of Ávila, located at an altitude of 1012 m, at the beginning of the Tiétar valley. It is surrounded by an extensive forest of chestnut and oak trees. If you want to know its resin past, I recommend visiting the ethnographic museum of Resin, which has two exhibitions, in two large resin huts.

Old construction that represented a well where food was stored for all the inhabitants of this area of the Sierra de Gredos. The place is preserved and beautiful!

The snow well has been restored and recalls one of the secular traditions of the inhabitants of the Alberche valley, when they stored ice in the heights of the mountains to supply the towns in spring and summer. Along with the ethnographic value, the geographical location of the building also stands out, installed in the reception basin on the north slope of the Casillas peak, where an impressive torrent of ice originated that modeled a V-shaped gorge in the Iruelas river, a sample of the most interesting characteristics of the geological values of the nature reserve.
