Sterling Hill offers Public Mine Tours for individuals and families according to their seasonal schedule. Guided tours last about two hours and include one hour in the underground zinc mine, half an hour in the large exhibit hall, and about 10 minutes in the museum of fluorescence.
In the Museum of Fluorescence minerals piled on open ore cars, with longwave ultraviolet lamps suspended above invite visitors to touch glowing minerals in the process of fluorescing. Many visitors discover that they themselves fluoresce, and that fingernails and teeth glow particularly brightly, often to disturbing effect. Handsome men, beautiful women, and cute children transform into ghastly creatures in this exhibit, they guarantee it, so talk to the kids about it before you go in!
Visitors are welcome to view their outdoor exhibits of mining equipment on the parking-lot level on their ownm but the mines can only be toured with a guide.
The museum features indoor as well as outdoor sheltered picnic tables, modern restroom facilities, a snack bar, and a fully stocked gift shop.

Please note that regardless of the weather or season it is a cool 56° in the mine, so make sure you bring with you a light jacket or sweater, even in summer. Sturdy footwear is also advisable. While in the mine you will be walking on a hard-packed gravel surface.
