Finish the tour above the waterfall because it is not visible! And enjoy the tunnels upstream (this being prohibited from the waterfall; landslides possible... bring a torch!)

This spot didn't impress me: "blue lake" is an exaggeration, it's a very small reservoir... lots of people on the banks too.

A short climb that allows you to switch between the two villages, on one side the Albarine Green Way, on the other the start of the climb towards the Col de Porte!

A very pleasant greenway along the Albarine River and the railway line! Ideal for connecting two different starting points for the ascent of the famous Col de Portes.
