To the south of the Ecrins massif, the Sirac is the last high summit at an altitude of 3441 m. It stands at the end of the Séveraisse valley, proudly showing off it best side: its 1500-metre high north face. During this walk, you will regularly raise you amazed eyes as if to salute this Lord and its crown. You will walk at its feet whilst being overlooked by its hanging glaciers. Simply magic!
