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 fly-fishing streams in the nation. 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.

The campground provides one accessible group site that can accommodate up to 40 people, with picnic tables, a campfire circle, grill and tent pads.

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 clearing surrounded by a forest of lodgepole pines. Grasses and summer wildflowers dot the landscape.

What you actually pay
Who keeps the booking fee
The agency’s own policy text says the reservation fee and the cancellation processing fee are “retained by the reservation service contractor”, and that a campground concessionaire will decline to refund them because “they did not receive these fees”. Recreation.gov is run under contract by Booz Allen Hamilton. What share of your booking fee the contractor keeps isn’t published in any federal dataset we can read, so we print no number for it.
