Cascade du Voire is a nice waterfall in gorge de la Diosaz, an one kilometer long gorge west of Chamonix in the village of Servoz. Gorge de la Diosaz is part of the national park « Réserve Naturelle de Carlaveyron » in the region Haute Savoie, France.
From Chamonix it is a 14 kilometer drive to Servoz over road N205. There are signs and the parking is easy to find (gps 45.931042, 6.769545).
From the parking it is 2,6 kilometer walk (roundtrip) along the river la Diosaz through the gorge. The elevation of the trail is 130 meter and good walking shoes are recommended. The walk takes about 75 minutes and you have to pay an entrance fee. More information is available on the official website of gorge de la Diosaz.
There are several small waterfalls and I am not sure which one is Cascade du Voire. One of the biggest fall is a waterfall of 15 meter under a small suspension bridge.
