Thanks to this route, go up the Gorges du Trient in the footsteps of the Flotteurs du Trient. History of the Floaters: In the past, the wood cut in winter was transported to the plain by the Trient river. During the descent, the wood accumulated in places. The peasant-floaters descended into the river to loosen the balls using "grespils", a kind of wooden poles fitted with iron spikes. The activity, very dangerous, regularly resulted in accidents. After going up the 6km of Gorges, you will discover the small typical hamlets of La Cretaz then Litro before reaching the village of Trient. From there, you will continue in the direction of the Glacier (source of the Trient) before returning to the Col de la Forclaz following the bisse du Trient, an irrigation canal built on the old railway line which was used for the exploitation of the ice of the Glacier du Trient, before the invention of refrigerators. This route will allow you to make a very beautiful trail outing, while discovering the rich industrial history of Vallée du Trient.
