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%.
