Overview

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 warming hut is surrounded by a forest of lodgepole pines. Grasses and summer wildflowers dot the landscape.

Recreation:

Big Springs is the headwaters of Henry's Fork and is one of the largest springs in the country. Henry's Fork is considered one of the best fisheries in the nation. Fly-fishermen cast for rainbow and brook trout. Tubing, canoeing, kayaking and rafting are also popular on the river.

The Big Springs National Recreation Water Trail can be accessed from the campground and ends 4.5 miles away at Macks Inn. It offers a lazy three-hour float or canoe trip through beautiful scenery. Wildlife, including moose, bald eagles and Sandhill cranes, are often seen along the trail.

The charming and historic John Sack Cabin is nearby, noted for its unique location, construction and furnishings.

Hiking, biking, horseback riding and ATVing are popular activities. Many miles of trails crisscross Island Park, including the Continental Divide National Scenic Trail and the Nez Perce Trail are in the area.

Facilities:

The warming hut can accommodate up to 200 people. It is fully enclosed and has a concrete floor. Several picnic tables are inside, along with a wood-burning stove for cool weather. Electrical outlets and overhead lighting are provided inside the building. Outside there are picnic tables, grills and a campfire circle.

A very large parking area is on-site, with 20-amp electric hookups on the edge. Please note that there is no water on-site, but it is available at Big Springs Campground 2.5 miles away. Firewood can be purchased there also. A vault toilet is located next to the warming hut.
