Information

Producing 120 million gallons of water a day, Big Springs is one of the country's largest springs, forming the headwaters of the Henrys Fork of the Snake River. The spring supports enormous rainbow trout which are protected from fishing. A .5 mile handicap accessible trail offers wildlife viewing of osprey, bald eagles, waterfowl and the occasional moose, white-tailed deer, and muskrat. Wildlife can be seen year-round although winter access is restricted by snow. The historic Johnny Sack Cabin site is located here, open from mid-June to Labor Day Weekend.
