Magnificent views if the weather is clear. Worth the climb and the detour.

The skyline is certainly impressive. And I love the reproduction of the Pico LLen tower.

The pity is that it can also be reached by car, but the views are very cool.

This climb is a beast, but worth it. First part is tough, but fine and offers nice views. Then you get some relief for a few hundred meters and see a warning sign with “18%”. This leads to a few hairpin turns that leave you thinking “this is doable”, but then the real deal starts. Long stretches of 15% and up without any recovery. It will test your willpower, but you feel accomplished when reaching the top and the view can’t be beat.

In the middle of the Peña Cabarga massif is perhaps the most popular peak in the park, Peñas Blancas offers amazing views in all directions. From its 455 masl you have no obstacles ahead, wherever you look.

The peak of the Peñas Blancas, a 450m high mountain south of Santander, a few kilometers from the coast. Two paths lead to the summit (only one is listed in Komoot), both of which are only a bit difficult for the last few meters. The summit offers good views over the Bay of Santander, Santander itself and the Atlantic Ocean to the north, while the Cordillera Cantábrica can be seen in the other directions, and the Picos de Europa on the western horizon.
