Las Llamas Park or Las Llamas Valley Park (officially Las Llamas Atlantic Park) is an 11-hectare urban park in the city of Santander, in the autonomous community of Cantabria (Spain). The first phase of this green space opened to the public on May 11, 2007. Another 426,000 m² are planned, extending almost to the border with La Albericia. Once completed, it will be the most wooded park in the city.

Almost 2 hectares, it must be beautiful on a cloudy day. I tried to skirt it but had to give up.

It is the main park and green lung of the city. A park that has it all, countless paths to walk, artificial lakes, fountains and everything you can imagine from a place like this. Wonderful to visit at any time of the day.

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).

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 oldest and largest of the two and can be accessed by a small slope to the right, briefly leaving the marked path (be careful in winter when it slips). It is a beautiful place to rest on its shore but the water cannot be used as a recreation area (no jet skis, no swimming, or anything like that).
