Lost Prairie Group Site is located along the Over the Rivers and Through the Woods Scenic Byway and is nestled among the forest in the Cascades at an elevation of 3600 feet. The Lost Prairie Group Area was originally a campground that has been converted to a group site. Every site has a picnic table and fire pit/grill. There is a parking area originally designed for the walk in sites that can be used for RV parking; this area is suitable for 3 large or 5 small RV’s, maximum 6 RV’s. There is one ADA accessible campsite. Reservations are accepted for reserving the whole park as a group facility. If Lost Prairie is not reserved it may be used on a first-come, first-serve basis for individual campsites.
