Robledo is like an oasis in the middle of the high peaks of the Villuercas. Although it enjoys a peaceful, almost flat terrain, it is surrounded by mountains of around 1,000 meters.
The geology is capricious and original; here the lines of mountain ranges that start from the massif are broken, the fluvial courses turn abruptly their direction making curves to get out of the closed gorges, the V-shaped cut of the rest of the valleys changes here to a pleasant peneplain.
