For a different walking environment, or a change of weather, head south from Rioseco to the Puerto de Tarna and to the southern side of the Cordillerra Cantábrica towards the reservoir at Riaño. Here you'll find Mampodre and other mountains in the Parque REGIONAL de los Picos de Europa.
See a route description of Mampodre in Spanish, and great photos which need no description!

This is not the same as the National Park!
If you want to walk and combine this with a visit to the beach, try Pienzu in the Sierra de Sueve near to Colunga or Arriondas -
