Saint-Marcel Mines: A Guide to Visiting Between History and Nature
Underground Galleries, Forest Trail and Mining Village: Useful Information to Plan Your Excursion
The Saint-Marcel Mines are one of the few historic mining sites in the Aosta Valley open to the public. For centuries, they extracted pyrite and chalcopyrite here. You can still walk through the same hand-dug tunnels at 1,720 meters high. You're surrounded by the remains of the village that housed the miners: homes, ovens, and even a mushroom farm. In the 1950s, abandoned tunnels were used for mushroom cultivation.
Visiting means discovering a lesser-known side of the Aosta Valley. It's often linked to skiing, spas, and alpine landscapes. But there's also its mining history and the hard work that shaped these mountains for centuries.
What to see at the Saint-Marcel Mines and how to plan your visit
Once you reach the town of Saint-Marcel, continue driving on the mountain road. It passes near the Plout Sanctuary. Park near the picnic area at Les Druges (1,585 m).
The hiking trail starts here. It leads to the Mines after about 45 minutes of uphill walking through the forest, near the famous Green Waters. This isn't for those seeking an easy hike. The best time is from May to October, when trails are snow-free and the weather is better.
We spent about three hours with an expert speleologist. He guided us along a scenic forest path by a stream, sharing the mine's history. Then we entered the tunnels. It was a short but unforgettable journey. Wearing helmets and boots was exciting, and the unique mineral formations were fascinating.
The visit continued outside, among the remains of the old mining complex. These ruins tell the story of those who worked here for centuries.
Access is only possible with a guided tour, and I highly recommend booking in advance. When we called, only two spots were left for the weekend. The visit costs 15 euros per person and lasts about 2 hours and 30 minutes. We ended up spending half a day on this experience. The forest trail and an extended stop to admire the Saint-Marcel valley--it's worth those extra minutes--made it all worthwhile.
