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

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.

From this small platform located in an elevated area next to the path, you have wonderful views of the Noja wells and with good visibility you can also see the coast of Santander.

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.

Beautiful place in an old mining operation. The wells were used to wash the iron ore, now giving rise to 2 artificial lakes, surrounded by an ideal environment for nature lovers.

The Wells of Valcaba are located at the foot of the southern slope of the Peña Cabarga massif and originate from mining in the area. This one in particular is the smallest and most "new" and located closest to the slope of the massif de los dos and can be accessed by a detour to the right marked by an information panel of the area with an explanation of the mining exploitation , the formation of the wells and the flora and fauna of the Peña Cabarga massif. You follow that path and you will reach the shores of the Lesser Well (today we did not reach the end because due to the floods of previous days the wells were a little overflowed).
