Back towards Grandfontaine

After 3 km of steep descent (be careful!), at the second hairpin bend on the right, take the little road going down to the right in the bend. Continue straight ahead for 1 km, keeping to the left all the way to Grandfontaine. You will come to the crossroads with the fountain that you passed on the way out. Go down Rue Principale to the left. From this point onwards, you will be retracing your steps.
