TOUR DU RATON

This panoramic route around the Cime de Raton (2,066 m) passes through a wide range of environments and surroundings, alternating between dense forests of larch, fir and spruce, and vast bare stretches of "pelites", these rocky strata, with their reddy colour, date back to the Permien (300 million years), and patiently carved by the waters of the Cians.
