Favor the climb via Sarcenas, almost no cars

The climb to the charming Som from the Col de Porte is always a treat. There are some very steep sections, but the view at the top is worth it. Be careful on the descent: uneven road, tight bends, cars.

Be careful, if in summer it is a fairly easy passage, in winter, as the surrounding slopes are steep, it is more prudent to have crampons

Folatière with only 1 "l", sorry... This magnificent block of limestone is perfect for catching your breath and enjoying the scenery. It is not a collapsed block; on the contrary, it belongs to the Urgonian slab that rises higher up to the summit of the mountain. The grooves that sculpt it are due to the subtle differences in the nature and cementing of the grains of the rock (the hollow areas are those that crumble the most under the effect of freezing and thawing). They show that it has bedding, despite its often very massive appearance." extract from Geol-Alp

Magnificent avenue of century-old ash trees. Unfortunately, as of 2022, more than half of them had to be uprooted, almost 2/3 because of Asian fungi dating from 2008 which make them fragile (they break and fall) and kill them. Link with global warming...very possible... The ONF is trying to save what is and replant...let's hope it works. From the Correrie museum to the monastery, about 1km and between 15 and 30 minutes.

Highest summer cheese dairy, perched in the middle of the Charmant Som mountain pasture. Well, okay, it's not really the season...

Dominating the valley, the Orgeval oratory offers a magnificent view. When the weather permits, the Mont-Blanc massif can be seen in the distance.
