Overview

Big Springs Group Area is located 22 miles south of West Yellowstone, Montana in beautiful Island Park, Idaho at an approximate elevation of 6,300 feet. Visitors love Island Park for its world-class fishing and outstanding scenery and wildlife viewing opportunities.

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.
