In a nutshell. Another remarkable underground experience. Abandoned in 1903 but now reopened to visitors, Sygun tells the story of Victorian miners. Nowadays, it’s hard to believe that such industrial heritage exists surrounded by so much natural beauty.

Why go? Take a self-guided tour of the old workings on foot. See stalactites and stalagmites as well as copper ore veins containing traces of silver and gold.
