Things To Do


Set aside a whole afternoon to experience this scenic and historic freshwater springs site. First recorded by the Lewis and Clark Expedition in 1805, it is one of the largest freshwater springs in the world, flowing at 156 million gallons of water per day! In this day-use park, you can picnic by the Missouri River, visit the fish hatchery and visitor center, walk along the Rivers Edge Trail, view nearby Rainbow Falls overlook, or visit the neighboring Lewis and Clark Interpretive Center operated by the U.S. Forest Service. Giant Springs Trout Hatchery is a production facility constructed in 1928. Reconstruction took place in 1984 when all the old round ponds were replaced by 24 outside raceways, except for one, which is now the show pond. The hatchery building was replaced and houses the egg incubators and 40 interior raceways, which can be seen from the visitor center. The North Shore Conservation Easement lands provide big, game, upland game bird and waterfowl hunting opportunities, but be sure to check for closures and limitations before you come visit.
