Giant Springs was discovered by the Lewis and Clark Expedition in 1805 and is one of the largest freshwater springs in the country. This is also the site of the Roe River, once listed as the world's shortest river. Giant Springs flows at a rate of 156 million gallons of water per day, with the crystal clear water staying at a temperature of 54 degrees year round. More than a quarter of a million people visit Giant Springs State Park each year. Visitors come to marvel at the remarkable springs and Roe River, or to view the variety of bird life. Some come to visit the nearby Rainbow Falls Overlook, to hike or bike the extensive trail system, and to visit the fish hatchery. A group picnic site is also available for rental.
The Montana Fish, Wildlife and Parks Visitor Center near the park features mounts of grizzly and black bears, educational features on fish and bird recognition, wildlife photographs, and a mini-theater that shows wildlife videos. The visitor center is open Monday through Friday 8:00am - 5:00pm.
The Lewis & Clark National Historic Trail Interpretive Center is adjacent to Giant Springs State Park and operated by the USDA Forest Service. The center includes numerous exhibits related to the Lewis & Clark expedition, a 158-seat theater, an education room for hands-on curriculum-based activities, and a retail store.
