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.
