Iola RV Park and Storage is located in Iola, Kansas, and despite the name of the business, they do offer some tent camping facilities: "Our tent area is secluded by trees and can accommodate approximately ten tents".
Iola is located at the southern end of the Prairie Spirit Trail State Park, a rails-to-trail that runs north-south for about 51 miles, from Ottawa in the north to Iola in the south (with plans to extend further south).
Amenities include picnic tables, grills, toilets, showers, and laundry facilities.
Cost for tent camping: $10.00
