If you're in the area, be sure to plan at least an hour. Parking is free. It feels like you're on another planet. The trails are very easy, you can visit the ruins of the windmill, and it's simply wonderful. Highly recommended, even with a dog.

Inside is some information on the history of the mine and an interesting overview map of the old mine tunnels.

What a surreal place to be at - partly an industrial mining tristesse, but then also an amazing range of colours in the sunset worth seeing.
