Sulens Mountain via the Sentier du Facteur

This is an unusual route to the summit of Sulens, which takes you up the steep grassy face of the east slope.
This trail is not "yet" marked on IGN maps... but is clearly visible on IGN Satellite.
A good reason to use it before it becomes too well-travelled...
At the summit: panoramic view of the Aravis mountain range, the Mont Blanc massif...

Description of the walk

Departure from the Col de Plan Bois.

(S/E) From the car park, take the tarmac road eastwards (towards Manigod) and follow it for about 500 metres.

(1) Turn right onto the wide track towards Sous Sulens, Les Crêtets and follow the signs for 'Tour du Sulens'.
Follow this track for about 2.5 km and after a few bends, you will come to a relatively flat section with the grassy face of Sulens on your right. At the foot of this, the meadow is dotted with rocks. About 300 m away is the Bois Noir chalet.

(2) Leave the track on the right and head north. Look for the trail (not very visible) but marked by cairns. Update 2020: signposts have been installed at this point - Sentier du Facteur, Croix de Sulens: follow them.
As you approach the slope, the Sentier du Curé has been cleared and is now well marked. It climbs in a zigzag pattern and leads to the summit ridge. Stay on the ridge (heading south-west).

(3) Pass the Croix de Sulens (1,828 m). Continue south on the ridge to reach the orientation table (1,839 m).

(4) The hike continues along the ridge to a small flat area.

(5) Take the dirt track on the right towards the Sulens chalets.

(6) After the chalets, the track widens and leads directly to the Plan Bois car park (S/E).

Notes

This hike should not be attempted if the route on the steep east face is likely to be snowy or icy.

Worth a visit

We are in the land of Reblochon cheese, so a quick stop at the Sulens chalet is a great way to enjoy some local cuisine (cheese available for purchase)!

This is a fairly short hike, but one that offers a lot of interest. The view of the surrounding mountains is beautiful: the Etale ridges, Aiguille de Manigod, Mont Charvin to the east and La Tournette to the west. The route is varied and pleasant. The climb up the Chemin du Facteur is certainly steep, but the path is well marked. The ridge walk is superb. the descent via the forest road can seem a little monotonous. Please note that the descent via the Chemin du Facteur can be dangerous if the ground is slippery (several accidents have occurred), so it is advisable to take this route on the way up. This is a wonderful route that can be completed in four to five hours at a leisurely pace, with stops to admire the view

A quiet route on this late August day

A superb family hike (but still quite challenging) done with children and grandparents.

The route is well signposted and the fact that it's a loop rather than a return trip is a real plus.

The grassy climb is short but steep, so don't underestimate this section if you're not very fit. (+370 m over approximately 1 km). The return journey is very easy and pleasant, passing by the orientation table. The descent is less steep than the return journey, so follow the directions on the map carefully.

I would avoid this loop in case of rain or if it has rained the day before, as the grassy climb can be slippery.

The views are superb and panoramic.

Elevation gain +610 m, duration 4.5 hours taking our time, but 12 km vs. 8.5 km indicated on the map.

Very steep climb up to the cross. Be very careful on the descent to the Col Plan de Bois, which is quite difficult with lots of gravel

Good description, except that now the start of the postman's path is marked by a pretty wooden sign and the path itself is very well marked. Be careful, it is narrow and the grassy slope very steep. It is worth pointing out that it is absolutely essential to avoid falling rocks for the hikers below.
After the summit of Sulens and the descent to the small pass that separates it from Petit Sulens, you can pleasantly choose to pass through Petit Sulens and then go around to the south to join a well-marked path (be careful, the start of the path is not very visible) to the Alpage Ecole.

Hello,
In response to the comment dated 10/07/24 regarding the possibility of using the factor's path in winter... The steep slope of the climb is impassable in winter in both directions. The path disappears under the snow and the slope is around 45°... any slip would be fatal.

A steep climb, but not very long, best done in cool weather... the rest of the loop is very busy.

A tough climb up the mountainside, challenging due to the heat and exposure, but what breathtaking scenery! And the view from the ridge over Mont Blanc, with a 360-degree panorama! A magnificent hike that will remain a wonderful memory of our time in the great outdoors.

A parish-specific to Brittany, very pleasant alternative route to climb up to the Sulens cross. The climb is fairly short but intense and quite exposed. Magnificent views. The path has been reworked recently but is still probably too difficult in winter, especially on the descent.

An excellent alternative to climbing the Sulens.
The scenery is absolutely magnificent all the way up.
Admittedly, the postman's path is a bit tough on the legs 🤣 but the beauty of the landscape and the fact that you're alone on the trail more than make up for it! 😎
Thank you for this great hiking idea 🙏

A very beautiful hike, very quiet during the week in the off-season, with a fairly steep section during the climb.

Superb hike. Doing it in this direction makes a lot of sense. The view once you pass the orientation table is more interesting: better view of Mont Blanc and a quieter picnic spot.

A beautiful hike, busy (it was a Sunday) but most of the hikers were doing the circuit in the opposite direction. In the end, the direction suggested here (with the "steep" part uphill) was much better suited to the soft, slippery ground caused by the previous night's rain.
Very beautiful view at the cross.
