Canyon du Llech, Slot canyon in Estoher, France
Canyon du Llech is a slot canyon in the Pyrenees featuring a sequence of waterfalls, natural rock slides, and water-carved pools. The flowing water has carved successive drops and basins into the limestone, creating a layered landscape of stone and moving water.
The canyon formed over millions of years as water gradually carved through limestone in the Canigou mountain range. These slow geological processes created the stacked structure of drops and basins visible today.
Local guides lead canyoning expeditions through the gorge, teaching participants about water flow patterns and regional geological formations specific to the Pyrenees.
Access requires physical activity and is typically done on foot through the canyon bed, with water often at ankle or knee height. It helps to wear proper footwear and protective gear, and checking water flow conditions before visiting is wise.
The canyon contains specific features named by locals, such as the washing machine water slide and multiple cascades reaching heights of 15 meters.
