Bisbee, AZ
Put on a hard hat, yellow slicker, battery-pack flashlight, and a back-in-time mindset and straddle the small train that transports you 1,500 feet into Bisbee’s once-booming copper, gold, and silver mine. As authentic as it gets, the tour is led by real-deal retired miners who recount quarry lingo and lessons learned. Reservations recommended, $13; queenminetour.com.
