The Col de Joux is a picturesque pass connecting the Ayas Valley to the central valley. The gradients to reach it, both from Saint-Vincent and from Brusson, are always manageable, but never negligible. The word Joux likely derives from a pre-Latin term meaning wooded hill. Others, however, maintain a Latin connection to the word Jugum, meaning yoke, and hence hill.

Now (August '23) there is a prohibition sign shortly after Col de Joux due to landslides, you are forced to go down to the valley. So in theory the path of the tunnels is forbidden; traveled last year, BEAUTIFUL.

The hill, as well as the path, is crossed by the high-voltage power line that transported the electricity produced by the French Superphenix nuclear reactor to Italy.[3]
