Big Springs is the name of a first-magnitude spring located in Island Park, Idaho in Fremont County. The spring produces over 120 million gallons of water each day.^[1] It is a primary source of the North Fork or Henrys Fork, and is famous for its large trout. Big Springs is the only first-magnitude spring that issues from rhyolite lava flows.^[2] It is a National Natural Landmark designated in August 1980. The spring is in the Caribou-Targhee National Forest and the site is managed by the National Forest Service.

Next to Big Springs is a log cabin built by Johnny Sack in 1929. The cabin is open to visitors.
