The chalet at Lac Besson on the edge of the lake of the same name.

The Besson lake chalet on the edge of the lake of the same name. Your crossing has reached its end. From here, you will take the same route to retrace your steps and find the Alpette and the cable car that will take you back to Vaujany.
It takes about the same amount of time to return, as the footpath has ascents and descents in both directions.
However, if you run out of energy to make the return journey, it is possible to get to the Poutran cable car station in about 30 minutes and take it on the way down. Once you arrive at the station of Oz, you will have to take another climb (7 euros) to return to the Alpette and finally take the cable car which will bring you down to Vaujany.
