10 km from Luchon on the Superbagnères road the Vallée du Lys, is the starting point for many scenic walks. The stream running through the Lys is a tributary of La Pique. Contrary to what one might imagine, the Lys Valley does not take its name from the flowers which she adorns every year in June. Its true spelling Batche det Lit, Valley det Lit, means Avalanche Valley. Since this magnificent spot, surrounded by high mountains, walks at various levels available to you. A few meters after parking, the cascade d'Enfer (hell) among the most beautiful in the Pyrenees. Later, after an hour of walking we arrive at the Gouffre d'Enfer. Still continuing, the Ru d'Enfer is an impressive projection carved into the rock by water. The more adventurous can learn canyoning supervised by an attendant. Walking to the meadow Artigue delight walkers.More experienced hikers will tour the lake (Green Lake, Blue Lake, Charles Lake and Celinda Lake). The Lys Valley is also the starting point for hikes to the high peaks Luchon. This is particularly the case of peak Maupas (at 3109m), both notable for its beautiful panorama that for climbing it offers on its faces South, West and North. Above the Lys Valley, in the mountains of Crabioules, mines were operated in the early 20th century. The original ore (lead, zinc blende) was sorted on site and down mule. An aerial cable dump was installed later, allowing greater exploitation. The ore was then treated in the laundry Valley, which today are ruins. The mining ceased in 1914, operating costs have become too high for optimal profitability. The action of the man in the valley is noted for the presence of the hydraulic unit.The water in Blue Lake and gate through the galleries and the penstock can be seen coming down the mountain, which causes the turbine operation. With 1419 meters of fall, this conduct is the largest in France. A cable provided access from the valley floor to the top of the pipe, but in order to reduce operating costs and visual impact dismantling is underway. EDF now provides the necessary interventions in a helicopter. Hiking in the mountains, even in low altitude requires some knowledge of the environment and a lot of precautions. Consider contacting professionals and check the weather forecast before leaving. In winter, many avalanche slopes that overlook the Lys Valley, impose vigilant.
