Description of the walk

Departure from the car park at Saint-Sulpice Church.

(S) From Saint-Sulpice, take the marked path that leads to both passes: Col Saint-Michel and Col du Crucifix. After 1 km, the path arrives at the hamlet of Les Michetons.

(1) Continue along the path uphill. After 500 metres, the path will split in two: a wide path on the right leading to Col du Crucifix, known as the Voie Sarde, and a path opposite, known as the Voie Romaine.

(2) Take the marked path of the Voie Romaine, which climbs diagonally up the side of the mountain.
At an altitude of 830 metres, a sign reminds you that you are on the Roman Way. Continue along this path, ignoring the trails that descend to Vimines. The Col Saint-Michel is now only 400 metres away.

(3) At Col Saint-Michel, read the information boards explaining the importance of this road in ancient times. Another signpost offers the option of visiting the FrançoisI Caves and Lake Aiguebelette.
Leave the Col du Crucifix and head first to the FrançoisI Caves. The trail takes you down to the caves in 15 minutes.

(4) A sign tells us that the king was forced to stay in these caves on his way back from a visit to the Holy Shroud, which was then in Chambéry. Continuing along the path, you will reach an intersection at an altitude of 855 metres.

(5) Make a 600m round trip to the left to the pretty viewpoint over Lake Aiguebelette.

(6) Return to the previous intersection.

(5) On the way back, we climb the Voie Sarde, this time towards the Col du Crucifix.

(7) At Col du Crucifix, take the marked path on the left towards Col de L'Épine, the third pass, which is about an hour's walk away.

(8) From Col de L'Épine, you can take the road that descends to the right to our starting point in Saint-Sulpice, but we're going to look for the paths that lead away from the tarmac. At the pass, facing our direction of arrival, you'll find a path that heads north. After 750m, it will lead to a hairpin bend in the road.

(9) Follow it south for 50 metres to take a path that dips to the left. It will soon lead to the road as well.

(10) Continue straight ahead on a wider path which, after 1 km, will take you back to the road above the hamlet of Les Tonys.

(11) Walk down the road to Les Tonys.

(12) Take a path on the left to descend into the valley, which will also lead to the road.

(13) Continue downhill, but this time the village of Saint-Sulpice is in sight, so all you have to do is descend (S/E).

Enjoy your hike, with a small bivouac possible between points 7 and 8.
Please note that water sources are few and far between.

Hello,
A very refreshing walk through the woods, completed safely with a dog in 3 hours and 40 minutes.
We stopped for lunch at the viewpoint below the Col de l'Épine, which offered a beautiful view.

A very varied route with superb views of the Aiguebelette slope. I extended it via Le Rocher du Corbeau before reaching Col du Crucifix.
No problems with orientation or route.
Thank you for this suggestion.

the route is easy to follow and well marked, except for the return to the small hamlet of "Les Tonys", but there was still about 1.5 km to go to reach the starting point by road.

Very shaded hike.
Interesting sections from 1 to 7: views, history of the tracks, cliffs.
Section between 7 and 8: be sure to take the marked mountain bike trail (which branches off to the left) and not the forest road (which is not pleasant at all).
At a place called Tonys (point 12), we couldn't find the path. We followed the road.

A beautiful loop with a lovely view of Lake Aiguebelette towards the François Ier cave. Otherwise, there are few views, but it is a pleasant walk in the forest. From the Col de l'Épine, a GPS is useful for finding the church and car park in St Sulpice. The directions in the last message are fairly accurate for the end of the hike and for avoiding the road.

I followed the signs to the Saint Michel pass.

I didn't go to the caves or the Aiguebelette viewpoint
It is possible to go directly to Saint Crucifix.

Heading towards Col de l'Epine, I missed the path to the west and continued straight on the main path

When I reached the Col de l'Epine, I followed the path behind the picnic area and continued straight on this path, which descends to a blocked road, and joined the main road on the right

When you reach Tonys, the path on the left in front of the house then descends to the right towards the forest, which leads to a stream. Follow the stream, cross it to reach a path and continue along the road towards Saint Sulpice

We left Saint Sulpice for the Col Saint Michel via the well-marked Roman road. The path is covered until you reach the pass. We descended towards Aiguebelette to see the viewpoint over the lake and the François I cave. The path descends gently for a long distance before you first reach the cave and then the viewpoint with its orientation table. You have to be careful not to miss it. Then we went back up to take the path on the left that leads to the Col du Crucifix and descended back to Saint Sulpice. The walk takes 2½ to 3 hours at a leisurely pace. We didn't go to the Col de l'Epine.
The trail is popular with trail runners and even mountain bikers.

Very nice local hike, but it's a shame that motorcycles are currently using this trail and damaging the Sardinian or Roman road by destroying its foundations.

A lovely, enjoyable hike. Thank you for this post!
Please note: If you are coming from Novalaise to reach the starting point in St Sulpice, the road is closed (for construction) about 10 km before St Sulpice. You must approach from La Motte Servolex. The duration of the construction was not indicated.
