Portal No. 31 Underground Mine Tour offers visitors the unique experience of touring an actual coal mine by rail car. Visitors will adorn the traditional protective gear of the coal miner as they enjoy animated exhibits along the tour. Outside Portal #31 stands a black granite monument in tribute to long time president of the United Mine Workers John L. Lewis and a memorial to U.S. Steel District #1 miners who died in mining accidents. The site also features a 1920s lamphouse, bathhouse, L&N train depot and loadout system.

Portal 31 is closed for the winter and will reopen March 1, 2013.

Portal 31 RV Park is located directly across from the Portal. With 12 hookups and 8 primitive parking spaces, the park adds another option for local accommodations. The park offers a sewer dump station for tour buses and RV vehicles.
