The park is located on the southwest shore of Flathead Lake and offers spectacular views of the Mission Mountains. It is a popular launch spot to Wild Horse Island. Many of the 40 campsites are situated along the shoreline. The park also has 3 yurts, showers and flush toilets. Swimming, sunbathing, boating, fishing and hiking on the nature trail are some of the popular activities. This park and the southern end of Flathead Lake are located on the Flathead Indian Reservation, so you will need a Confederated Salish and Kootenai Tribe fishing license to enjoy the excellent fishing here.
