Venture 100 feet underground to see the original shaft station and the Orphan Girl vein, one of the few exposed veins in North America that can be seen by the public. The tour guides lead you through the drift, sharing stories as you venture 100 feet into the 2700-foot-deep Orphan Girl Mine. Many other surprises wait for you at the 100-foot level.

What to Expect:

  • The Orphan Girl 100-foot level tour takes you to the original workings of the mine. Mud is likely.
  • This tour is an all walking tour.
  • Visitors are fitted with miners’ hard hats and cap lamps. The cap lamps are the only lights underground except for two, which are used to highlight the shaft to the water.
  • The mine workings are not ADA compliant and walking 180 feet of entrance ramp is ordinarily required; however, visitors with limited mobility may be accommodated for much of the tour. There is a 22% slope although there are no stairs.
  • ANY participant has the option to turn around at any time.
  • General admission included with purchase of Underground Tour ticket. Guests may tour the 22+ acres of Museum prior to or after their guided tour. (Guests on the 4:00 tour are recommended to come prior as the Museum will be closed at the conclusion of the tour.)

What to Bring:

  • Closed-toed walking shoes and light jackets are recommended.
  • Face coverings are required. The gift shop has some available for purchase.
  • Members must provide proof of membership at check-in.

Guided tours offered Tuesday – Saturday. Underground Tour availability may be limited after Labor Day.
