Lagunas de Neila is an impressive group of glacial lakes. The most spectacular glacial valley is the one shaped by the dark waters of two major lakes: the Laguna Negra and the Larga. The valley of the Laguna Negra is the largest and most perfect formation of its kind in Spain. A beautiful cascade flows from here and in wintertime gets frozen conforming a spectacular scene. Just below the valley, many other glacial formations arise, first Laguna de Las Pardillas and then Nicho del Contadero, where another two lakes were created: Los Patos and Brava.
