From Vicdessos we followed the valley floor to Auzat, then turned to ascend towards Marc.

Marc was a very old settlement, clinging precariously to a large boulder, left by the Vicdessos river during some glacial retreat. Beyond Marc, the road became a track, suited more for mountain biking without luggage, and really started to climb.

Several hours later, the track ended at around 2000m and become a narrow footpath. The footpath would not have been ridable even if we'd had the energy left!

So we deteached the panniers from the bikes, and climbed the final 500m twice. First with the bikes, then back down to bring up the panniers (2hrs).

The inhabitants of Andorra seemed to expect a road link to France one day!

The descent on the unmade track was short and it soon became a wide new road to Andorra la Vella with a good smooth surface.
