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.
