The passage through the tunnels of the old railway line... it's fun! In addition the road is small and nice, and when I went there it was closed to traffic... as long as it stays that way it's perfect!

The Port of Lers is a crossing point which offers a beautiful panorama where you may be lucky enough to see Mertens black horses. It is also a place which has seen the Tour de France pass many times.

The climb is on an off-center road, so little traffic. The ascent is partly in the shade and offers some breathtaking landscapes during certain turns!
