The name comes from the stone boundary markers erected in the 18th century to demarcate lands acquired by Charles III for hunting. During the Spanish Civil War, it was a strategic area with a Republican detachment stationed there. It formerly housed the Valcotos ski resort, which no longer exists.

Mountain refuge near the Laguna Grande de Peñalara, with spectacular views of the surrounding area. It's worth returning from the lagoon to the reserves, passing through the refuge—the views won't disappoint.

Tired from the climb, you sit down sheltered from the wind and eat a snack. If it's not windy or cold, look toward Peñalara and make out the landscapes and lagoons. Look toward the Bola del Mundo and admire the scenery. Look toward La Cuerda Larga and explore its grandeur.

True! A good place to observe the peaks of the Cuerda Larga and learn the names of the peaks. The route along the Cuerda Larga is spectacular, but you can see how much snow there is now. The route is very beautiful, but it does involve some risk, but when it thaws, the route is safer. But with good equipment, the snow is incredibly attractive.
