Despite the chilling photos, the Cravate passage is not very exposed as long as there are no snowfields left to block the road (you can see them from La Roche sur Foron, which is quite practical as a local). Of course you shouldn't be afraid of heights but this path can even be crossed by running! So no worries

A majestic summit resembling a pyramid from the Cenise side, the Jallouvre - or Jalouvre - is a mythical summit whose ascent, although not difficult compared to its neighbor Pointe Blanche overhanging it by 30m, remains in the memory like that of a almost epic adventure between grueling scree (on both sides), the mythical Col du Razoir (the aptly named) and the Passage de la Cravate which, in the end, poses no more problem than that when the residual snowfields have disappeared, unless that we are subject to vertigo. In summary, one of the most beautiful hikes in the area in my opinion, for which you still need to be sure-footed and in good shape, but which can be tamed quite easily. Do not miss !

Very popular spot in summer. If you have a little strength in your legs to spare, don't stop at the lake, go up to the Balafrasse pass which gives a breathtaking view of the first as well as the Aravis range and Mont Blanc.

Much more aesthetic path than the usual path, it is however not recommended in case of vertigo

A few more 300m to climb from the lake but a fairly impressive panorama of the Aravis and Mont Blanc that you can't see from below. The climb is steep at the end but nothing very difficult (except perhaps the crossing to the summit cairn)

Because it’s pretty and in summer, there are even cows that make very beautiful Reblochon

Very pleasant welcome but in my opinion, remember to book, a real highway Lake Lessy in summer!
