Things to do:

The spring flows at a rate of 156 million gallons of water per day and is always 54 degrees Fahrenheit! Multiple bridges cross the crystal clear water that makes up Giant Springs, allowing visitors to peer in and see the growing vegetation and even an occasional fish!

While you won’t find any camping at Giant Springs State Park, you won’t find the park lacking in activities! The Roe River (also found in Giant Springs State Park) was once listed in the Guinness Book for World Records as the world’s shortest river!

  • Visit the fish hatchery and visitor center.
  • Take a walk on the Rivers Edge Trail.
  • Go on a hike along the many trails hugging the Missouri River.
  • Take in the Rainbow Falls at the overlook.
  • Visit the Lewis and Clark Interpretive Center, located nearby and operated by the U.S. Forest Service.

The water found in Giant Springs comes from the Madison Aquifer under the Little Belt Mountains. Because the water stays around 54 degrees year-round, Giant Springs State Park is great to visit regardless of the season!

In the winter, the steam rises off of the unfrozen water and birds flock around the warm water, while in the summer, the park is, on average, 20 degrees cooler than the nearby city of Great Falls.

Did You Know

Curious what other visitors have had to say about the park?

"Absolutley beautiful place top visit. Especially during spring and summer time. Trail access is easy from here and is a must see for anyone paying through or visiting."

"This is by far the best park in Great Falls and has a lot of good history posted around the park. There is a very clear natural spring, a playground for the kids, lots of barbecues and picnic areas. Just don't leave a mess like some of the tourists do.. throw your trash away and keep this place looking nice."

"Turned out to be a great Sunday to visit the park. Sun was shining, no wind, 38 degrees out but it felt great. Picnickers we're about. Nice "museum" for the hatchery. Got to feed some really big rainbow trout."

"This is a must see attraction if you visit Great Falls. The trout hatchery, the kids pond, the amazing views, and excellent fishing right from the park. We had our engagement photos done here as well. Bring a picnic lunch and spend the day."
