A sports via ferrata "à la française", running through the drops on the north side of the Tête aux Chamois: numerous extremely exposed traverses, and in between these shorter vertical passages. Essentially, it follows a series of natural ledges, comfortably wide in places, but often narrowing until just wide enough to take a foot; the traverse of the "Rocher Jaune" is guaranteed to set your hair standing on end. An unusual feature is that you climb down to the start, and from the finish you climb up to the cable-car. The via ferrata extends over about 800 metres.
The concept of the Via Ferrata came about in Italy and was largely developed in this country. A variant of rock climbing, it involves following a route through the rocks, equipped with a double-length safety rope.
This walk through the mountains is unique, taking you through several different types of countryside.
