My husband and I recently did the Queen Mine tour, and we both agree this was a fantastic experience, well worth the time and money! What a great experience to take the train 1500 feet into the mountain. Sure it's dark, but not overwhelmingly so. And each person is wearing a bright miner's lamp that you can aim wherever you please. I thought perhaps I might feel a bit claustrophobic, but that did NOT happen at all. Two miners led the tour with us and did a great job of explaining how mining was done back in the days. Highly recommend this experience! And the mining museum in Bisbee is a great place to start to get the background first.
