The Vercors mountain range, in the extreme west of the French Alps, looks like an oversized Trutzburg. A landscape with deep, rugged gorges and wild rock falls, widely branched cave systems and dreamy little villages. This difficult-to-reach mountain range with peaks up to 2,350m height can still only be explored today via narrow and bold roads. Only at the beginning of the 20th century the area was opened up with the help of sufficient dynamite. I In vertical rock walls galleries were blown up and some of the most spectacular mountain roads were created, such as the “Gorges de la Bourne” and the “Combe Laval” }>
