Things To Do


The largest island in Flathead Lake preserves an endangered Palouse prairie environment, incredible wildlife, and historic resources. Boat access is required to reach this day-use-only 2,000-acre island. The island's scenic shoreline is a favorite of hikers, boaters, swimmers and sailboat enthusiasts. Day-use only is allowed, and there are other strict rules to ensure maintenance of its natural character. 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. Wild Horse has been a landmark rich with history since the Salish-Kootenai Indians were reported to have used it to pasture horses to keep them from being stolen by other tribes. Check with park staff on the best ways to reach the island and its trails and views. Private property is found along the perimeter of the island. Rare and endangered plant species have also been found on its Palouse prairie grasslands. There is a composting toilet at Skeeo Bay.
