Giant Springs State Park, Great Falls

#2 of 16 in Things to do in Great Falls
Giant Springs is a large first magnitude spring located near Great Falls, Montana and is the central feature of Giant Springs State Park. Its water has a constant temperature of 54°F and originates from snowmelt in the Little Belt Mountains, 60mi away. According to chlorofluorocarbon dating, the water takes 50 years to travel underground before returning to the surface at the springs according to the placard at the state park.Giant Springs is formed by an opening in a part of the Madison aquifer, a vast aquifer underlying 5 U.S. States and 3 Canadian Provinces. The conduit between the mountains and the spring is the geological stratum found in parts of the northwest United States called the Madison Limestone. Although some of the underground water from the Little Belt Mountains escapes to form Giant Springs, some stays underground and continues flowing, joining sources from losing streams in the Black Hills, Big Horn Mountains and other areas. The aquifer eventually surfaces in Canada. Giant Springs has an average discharge of 242cuft of water per second or 150 million gallons per day.

    An amazing park to bring your family or dog to. Great trails go from it to both directions of the river for running, biking, or just walking.

    This is a beautiful state park. It's free for Montana residents and $6 per car for everyone else. In addition to the springs there are hiking trails to the waterfalls and a fish hatchery with self guided tours. Lots of terrific photo opportunities here.
