Tannes et glacières du Margériaz (Tannes and ice caves of the Margériaz) is a sentier karstique, a karst trail. Located on the eastern slopes of Mont Margériaz above the village Aillon-le-Jeune, it is reached by following the signs to the skiing area Margériaz 1400. At elevations about 1500 m asl, it is accessible only during summer when there is no snow. It is named after the typical caves on the limestone plateau of Margériaz, the tanne. Tanne is the local word for pothole, and it is not French, it's the local Savoien dialect. The karst trail has 9 stops, one of them is a semi-wild cave which is equipped with trails and ladders.
Actually there are two different circles, a long and a short circle. Tor use the short circle turn off at the Bergerie chalets at point 4, on the Grand Raffou (1590 m asl). It's also possible to extend the tour at stop 6 to the ridge and then to the summit of Mont Margériaz, about 100 m higher.
There is no restriction to the path, but It's difficult to walk if there is snow, so it is realistically open only if there is no snow.
