Welcome from the Hardin KOA! Come see all we have done in our first 2 years. Many upgrades, including a 24-hr laundry, 2 huge dog parks, a dog wash and a mining sluice. We have an after-hours, night registration box. Office # (406) 665-1635. Office hours 8 am to 8 pm MST. After hours # 971-322-3239.
The Hardin KOA is halfway between Yellowstone National Park and Mt. Rushmore. Come and stay with us and enjoy all that our area has to offer. You'll be glad you did!
