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.
