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.
