The Minnetonka Cave is nestled within the expansive Caribou-Targhee National Forest.

This massive forest encompasses over three million acres of land with breathtaking landscapes and extraordinary Idaho terrain stretching to the borders of Montana, Utah, and Wyoming.

The area offers ample outdoor activities like snowmobiling, horseback riding, and all manner of fishing, from trout to steelhead, in nearby streams and rivers.

The national forest also has its own unique history. It was created in 1908 when President Roosevelt set aside 168 million acres of untamed western land to create the first National Forest Reserve. There are also several hiking trails that you can explore within the park near Minnetonka Cave and St. Charles.

Keeping Bats Healthy

Due to the westward spread of White Nose Syndrome (WNS) in bats, certain restrictions are in place at Minnetonka Cave. Adhering to the restrictions set in place by the caves helps to preserve the cave’s condition and protect the bats from White Nose Syndrome.

Visitors are prohibited from bringing any articles of clothing or backpacks. This helps to prevent the WNS from spreading and affecting the bats.

Planning A Succesful Trip to Minnetonka Cave

When planning a trip to Minnetonka Cave, visitors should make note of the particular limitations and protocols put in place to ensure the cave stays preserved.

  • Photography: Visitors to the cave need to be aware that cameras are allowed, but not tripods. It is also important to note that the cave is well-lit, so no additional lighting is necessary.
  • Clothing: The cave can get fairly cold, so visitors should be sure to dress appropriately. Pack long sleeves and pants for the 80-minute tour.
  • Exercise Caution: Lastly, please use caution when traversing the stairs, and wear appropriate shoes with good traction and ankle support.
  • Pack Snacks: Be sure to bring plenty of water and snacks for before or after the tour as there the closest dining is back in Bear Lake!

Cave Accessibility

The cave is unfortunately not amenable to those with physical disabilities or mobility issues because of uneven ground and slippery surfaces.

It requires a trip down 896 steep stairs, and these steps can be wet and slippery in places. To ensure safety, visitors are advised to take great care when navigating the stairs and use the available handrails.

For those unable to make the journey, there is an observation area with a spectacular view of the cave entrance to enjoy.

Fitness Requirements

The tour will take you on a challenging yet rewarding journey deep below the Caribou-Targhee National Forest. You’ll navigate nearly a thousand stars roundtrip and a total length of 0.8 miles. Although this is considered a strenuous tour, your experienced guide will stop and provide rest stops every five to six locations to make the trip enjoyable.


Though it would be fun to take fido down into the depths, pets are strictly forbidden inside the cave. The cave is considered a precious natural wonder of the area, and follows protocol to keep it pristine and preserved.

Foot Washing Procedures

At the entrance of each cave, visitors will be guided to the foot wash station. Here you’ll remove any footwear and wear the provided booties after washing your feet with the provided solution.

This foot-washing procedure must be completed before each cave visit to ensure the safety of the caves’ species.
