Meters before reaching the Port or Portillo de la Sía, at 1,200 m. altitude, we find the Mirador, from where we have impressive views of the Soba Valley.

From here the main routes of the Collados del Asón Natural Park begin. This car park is usually full on weekends and you can also park on the other side of the road
