High above the valley you can still find traces of dinosaur footprints from 250 million years ago.
Lac d'Emosson is worth a visit in itself, the dinosaur footprints are an added bonus. An immense hydroelectric dam perched high above the Franco-Swiss border, the dam forms a large blue lake with walking paths and forests all around. The views are superb and you can't fail to be impressed by the height of the dam walls (180m), which have been used as a launch pad by base jumpers in recent years.
Guided tours of this site are available in July and August each year, with a geologist from the Natural History Museum of Geneva, or you can do the hike of your own free will, you just won't get the explanation about the footprints at the end!
