Things To Do

Overview

RV and tent camping, rental yurts and a nature trail are all here along the shore of magnificent Flathead Lake. Flathead Lake was carved by receding glaciers 10,000 years ago and is the largest natural freshwater lake west of the Mississippi. Using the public ramp to launch your own boat, this site is a popular jumping-off point to Wild Horse Island. Mature ponderosa pine and juniper trees provide a beautiful setting for the campground. The beach is popular with sunbathers and swimmers, while the nature trail provides excellent birdwatching opportunities. Camping and yurts are available from May 1 to September 30, however the park and boat ramp are open all year. Please note: There are no ADA accessible campsites at this park. This park and the southern end of Flathead Lake are located on the Flathead Indian Reservation, so you'll need a Montana fishing license and a Confederated Salish Kootenai tribal fishing license to enjoy the excellent fishing here.
