Hike to dinosaur footprints at Emosson dam | Switzerland

Ancient reptile tracks & two beautiful lakes | Thrilling mountain train option

Medium loop hike (T2)

OK, so the footprints aren’t really those of dinosaurs — they are actually from primitive reptiles that predate the “terrible lizards”. At 240 million years old, these are the oldest fossil vertebrate tracks in Switzerland. They are not as obvious as I had imagined (hoped?) — but the area is very beautiful, with two high dams (Lac de Emosson and Lac du Vieux-Emosson) and views of the Mont Blanc massive. If you have time, you can also add three quirky mountain train rides to your day.

To be sure of seeing the footprints, go after mid-July — otherwise they may still be under snow. Guides are present in late July/August to provide information about the site.

The hike described here is a loop; see the nearby mountain fun section for other options.

Getting there & away

The dinosaur footprints hike starts and ends at Lac d’Emosson (or Emosson dam), in the Swiss canton of Valais/Wallis. The lake is only accessible by road and public transport between mid-May to mid-October.

You can drive up to the Emosson dam or take a train to the village of Finhaut, followed by a bus. Alternatively, take the three mountain trains operated by VerticAlp Emosson from the village of Le Châtelard.

Trail description & map: Emosson dinosaur footprints

The trail is clear, well marked, and not too steep or exposed. It starts as a paved road from Emosson dam to Lac du Vieux-Emosson (T1) then becomes a mountain trail for the rest of the way (T2). There may be some snow on the track in early summer, but you should be able to cross it with regular hiking shoes.
