My family just did this. It is truly world class and we have travelled the world so this was a pleasant surprise. Much more interesting way to spend 2 hours than whale watching. The people there are wonderful, very friendly and entertaining and extremely knowledgable about the history of mining. Ride into the mine do some mining and see the very well done Av presentation. A real bargain compared with what you can pay elsewhere for attractions which are often very amateurish.
