Take the time to climb a little higher than at the Bastille, because it's impressive.

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

Easy and very pretty, a 360° as we like them in Chartreuse

Excellent hike with views of the Belledonne mountains and, if the weather is good, Mont Blanc. The climb to the Moucherotte is not particularly demanding, but the hike is very scenic and the view from the summit is a highlight. On the way down, you can take a detour over the dilapidated ski jump from the 1968 Olympics.
