Ordesa — Cola de Caballo to Refugio de Góriz

Ordesa y Monte Perdido is the crown jewel of the Spanish Pyrenees. This iconic route takes you through the deep glacial valley of Ordesa, passing the 'Gradas de Soaso' waterfalls to reach the 'Cola de Caballo' (Horsetail Waterfall). From there, the trail ascends steeply up the 'Clavijas de Soaso' (iron pegs) or the 'Senda de los Mulos' to reach the Refugio de Góriz (2,200m). It is a journey through massive limestone canyons, ancient beech forests, and high-alpine plateaus under the shadow of the 3,355m Monte Perdido.

The trek to Laguna de los Tres is one of the primary day activities in Los Glaciares National Park, providing a close-perspective view of the granite massif of Mount Fitz Roy (3,405m). The route follows an out-and-back trail through mixed forest and glaciated valleys, passing the Piedras Blancas viewpoint before the final ascent. The journey is defined by a significant transition from the low-lying valley floor to the high-alpine environment of the lagoon, which sits directly below the main peaks.
