Cascade de la Meije is a powerful twin waterfall fed by the glacier de la Meije located in the village of La Grave, near Briancon, France.
From la Grave there is a small road heading to the river. From here you should see the waterfall. There is also another path, from La Grave, heading to the top of the waterfall, probably going to the glacier.
The waterfall looks very impressive and great, have to check it out next time when I am going to France.
It is also possible to go by cable (Téléphérique de La Grave) to glacier de la Meije. You will have an awesome view on the valley and as far as I can see you will see another part of the waterfall (or another one???).
