The Dame Blanche viewpoint The Saut de la Forge Saut-Girard waterfall Signpost at the start of the walk


Starting from the car park in Ilay, follow the trail (GR559A) downhill to the first waterfall (Saut Girard). (1) At the bottom of the Girard falls, cross the river and follow the track along the left bank. The path is wide and easy at first but can get slippery after the Saut de la Forge. It becomes slightly steeper but is well maintained.
Continue downstream to the Sarrazine footbridge (2), then follow the yellow waymarks and continue towards "Bonlieu". (3) Here you can follow the barrier to admire the view. On the way back, just before the end of the barrier, turn right towards Bonlieu. The uphill path is a bit narrow and very steep on the right, so be careful!
When you are almost above the cliff, you can either continue directly to Bonlieu, or take a detour to the Dame Blanche viewpoint (definitely worthwhile) (4). To get there, follow the yellow waymarks which lead to the viewpoint, then on to Bonlieu.
(5) Go through the village, first taking the rue de la Maison Blanche, then the main street taking you to the other side of the village.
(6) When leaving the village, follow the GR signs up a small road, which becomes a track then a forest path.
The GR markings will lead you back to your starting point via the Girard falls (1).

Hello! Tried to follow this rout, but the footpath is closed where you should turn away from the river, just after way point 3. Very sad

Without doubt, the shortest path up to the summit of La Dôle (1677m altitude) from the French side of the border. In good weather, the views are breathtaking and go on for over 250km: from the Swiss Alps to Mont Blanc and on to the Vanoise and the Ecrins, all of this with plunging views down over Geneva and its lake.
