Vieux Emosson Geology Trail (Dinosaur Tracks)

From the dam the trail climbs a stepped ramp up onto the upper cirque, where the Vieux Emosson reservoir sits below the pink slabs of the Aiguilles Rouges. The dinosaur trackway itself is on a large sandstone bench above the north shore, signed and easy to miss if you don’t look. On a clear day the Mont Blanc massif fills the whole southern skyline.
