Access by car
From Geneva and Lausanne, take the A9 motorway, exit 21, then follow signs for Fully, Buitonne and Chibo. At Chibo, continue straight on and follow the track to its end. From Fully, the road and track are relatively steep and narrow. Passing places have been provided. It is advisable to use a vehicle that is not too bulky. Car park: the large Erié car park, at the end of the track coming from Chibo.
