La Thuile Mine is not a show mine, at least not the kind with helmet, lamps and an underground tour. The slopes of the Cole della Croce, above the suburb La Thuile, are full of mining remains, including mine railways, tunnel mounds, hoists, and ruins of the shelters used by the miners. The area has eight walking trails of different degrees of difficulty and length, which lead to the numerous remains. The shortest is only half an hour walk, the longest more than 4 hours. The trails are well-marked with trail number and each route has its own colour and there are educational signs in Italian, French, and English, so it is rather simple to do the walks on your own. If you prefer a guided tour, you should make a reservation with zerovertigo mountain guides. For obvious reasons the trails make only sense during summer and early autumn, though you could do some with skis during winter too. However, the visit is always weather depending.
