Wieliczka Salt Mine

Located a 20-minute drive from Krakow’s city center, Wieliczka Salt Mine dates back to the 13^th century, making it one of the world’s oldest salt mines, and only ceased production in 2007. A UNESCO World Heritage Site, the mines, which are located over 400 feet underground, can be visited in three-hour tours, during which visitors can see the incredible chapels (complete with salt chandeliers) and dozens of statues that were carved by the miners while they worked. The mine, which is also known as the “Underground Salt Cathedral of Poland,” is one of Krakow’s most fascinating places to visit.

Note: You must walk down about 800 steps to enter the mines (there is an elevator on the way out).
