On our last day in Wales we stopped by the Llechwedd Slate Caverns near Snowdonia National Park and took the two underground mine tours. These slate mines are no longer used for mining, but have been a tourist attraction since the 1970s. The guided tour took us through mines that were first dug in the 1840s and demonstrated the mining techniques they used back then. Jack and Lucas loved riding on the small train through the tunnels, wearing their hardhats.

As with other kinds of mining, slate mining is very hazardous; many people were killed in these mines during their 130+ years of operation.
