About this campsite

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 concrete boat ramp with docks is located between the group camping and single family camping loops. Access to the campground is on a paved road but the interior loop roads and parking spurs are gravel. Natural Features

Island Park is composed of two areas of extinct volcanic activity. The Henry's Fork Caldera sits inside the larger Island Park Caldera. The area is known for its dense forests of lodgepole pine, broad grassy meadows bursting with summer wildflowers and a wide variety of wildlife, including black and grizzly bears, moose, elk, deer, bald eagles, Sandhill cranes and much, much more.

The campground is situated in a forest of lodgepole pine, which provides partial shade in some sites. Some areas of the campground are more open and sunny than others. Nearby Attractions

Mesa Falls Scenic Byway is 13 miles south of the campground. This 28-mile road leads to scenic overlooks and trails at 110 foot Upper Mesa Falls and 85 foot Lower Mesa Falls.
