About Buttermilk
Overview Buttermilk Campground is located approximately 30 miles southwest of West Yellowstone, Montana and 32 miles north of Ashton, Idaho in beautiful Island Park, Idaho. Buttermilk sits next to Island Park Reservoir at an elevation of 6,200 feet. Visitors love Island Park for its world-class fishing and outstanding scenery and wildlife viewing opportunities. Recreation The Island Park area is prized for its fishing; the Henry's Fork is known as one of the nation's best fly-fishing streams. Anglers cast for rainbow, cutthroat and brook trout and Kokanee salmon. Island Park Reservoir offers boating, water skiing and excellent fishing opportunities. The reservoir is used for irrigation so the water level recedes throughout the summer, but is generally useable all season. Henry's Lake is nearby. Hiking, biking, horseback riding and ATVing are popular activities. Many miles of trails are in the area, including the Continental Divide National Scenic Trail and the Nez Perce Trail. The Big Springs National Recreation Water Trail offers an approximately three-hour float or canoe trip through beautiful scenery. Wildlife, including moose, bald eagles and Sandhill cranes, are often seen along the trail. Facilities The campground contains two loops for single family camping and one loop for group camping, with a total of 55 sites. The large group site can accommodate up to 150 people. Site 038 has 15-amp electric hookups. Vault toilets and drinking water are provided. A concret
