Discovered in 1937, Mystery Cave is the longest cave in Minnesota! It covers over 13 miles of underground passages that were created as moving water dissolved the rock. Each tour takes you underground through different parts of the cave, and will showcase features like stalactites, stalagmites, flowstone, fossils, and beautiful underground pools as your tour guide explains how the cave and these features were formed.

  • Cave tours are held 10 AM to 5 PM from Memorial weekend through Labor Day. All tours require reservations; some require special advance arrangement with the park. (See individual tour information below.)
  • Reservations may be booked 24 hours or more in advance, but there are no same day reservations. Any unsold tickets are available for purchase at the cave on a first-come, first-served basis on the day of the tour. Reserve online or call 866-857-2757. Groups call 507-937-3251.

About White-nose syndrome and the bats in the cave

A fungus that causes White-nose syndrome (WNS) in bats has been confirmed at Forestville/Mystery Cave State Park. WNS is a disease that is killing hibernating bats in eastern North America. It is believed that more than 5.7 million bats have died as a result of the disease, so far. WNS is not dangerous to humans or other animals. It is transmitted primarily from bat to bat, but can be spread by people and animals who visit infected caves or mines.

Public tours of Mystery Cave will continue. To help keep the fungus from spreading, visitors are required to walk across special mats designed to remove spores from footwear. Visitors are advised not to visit other caves or mines with any clothing, footwear or other gear they have used in areas where WNS or the associated fungus is present, because washing alone cannot sufficiently disinfect clothing.

Learn more about White-nose syndrome and what you can do to help slow its spread.
