Do I need a coat for the Mine?

The mine is consistently 52 degrees, and wet. Our guides tend to wear jackets while giving tours throughout the day. Your tour will last 30 minutes. 

How accessible is the Mine?

There are 33 modern steps to enter the mine. The standard 30 minute tour leads visitors around a 100 yard loop starting at 35 feet below ground and descending to 75 feet below gorund. The slope is gradual, and there is an anti-skid coating on the floor, but the footing is uneven and slanted. Closed toed shoes are recommended. The shortest tunnel is 4 feet, and required visitors to walk through it is they wish to experience the full tour. Strollers, wheelchairs, walkers, and similar devices are not permitted in the mine. We ask visitors to consider their medical history and physical limitations before descending to the mine. Take a virtual tour of the Mine here (external link)

Is there parking at the Museum?

Yes there is a large parking lot just north of the property and has marked accesible parking spots. There is also an overflow parking lot south of hte property, which does not have accessible parking spots and has a trail leading to the visitor center. During large events, visitors will be directed to park in the field across the street.

What can I see when the museum is closed?

After hours and off-season, visitors can explore the exterior perimeter of the prison walls, as well as enjoy the picnic area with an incredible view. Please remove all food from the premesis to avoid any bear visits. 

When will Viets Tavern be open?

We recieved $750,000 from the National Park Service, Semiquincentennial Grant to rehabilitate Viets Tavern. We anticipate the project to be completed in 2026, and will keep our community apprised of next steps to allow public access. Take a virtual tour of Viets Tavern here (expernal link).

Will I see a bat on my mine tour

Our bat population hibernates in the Copper Mine from November through March, which is one of the reasons we close the site during the winter. Occasionally a bat will wander into the Mine in September or October to scout out their hibernation location. 

Is the site haunted?

What do you think? ;) We choose not to engage with the paranormal as part of our regular interpretation. However, we recgonize that this topic is important to a lot of people and we encourage you to visit the site and make your own determination.
