The Cascade du Dard is a nice waterfall located near the Tunnel du Mont Blanc entrance and not too far from the center of Chamonix. The Buvette de la Cascade du Dard is a very nice snack bar located right next to the waterfall that serves salads, omelets and cheese fondue. The waterfall and the snackbar together form a great little destination for the family. Just mind the kids as they are likely to want to go to the base of the waterfall and that area is quite rocky. There is also a sign warning you of potential flash floods. 

The water of the Cascard du Dard comes from the Torrent du Dard, a little river which forms high above the waterfall at the foot of the Glacier des Pelerins. From the waterfall the water flows further downstream in a northern direction till it meets the big Arve river near Les Pelerins.

Reaching the waterfall is easy. There is a parking very nearby about half way up to the entrance of the Tunnel du Mont Blanc. This would enable you to visit the snack bar and the waterfall is less than 10 minutes. You can also walk it from the valley floor in which case we suggest the trail that starts at the Grepon Parking near Chamonix Sud in which case the walk there and back will take you between 1 and 1.5 hours.
