Tour Overview
A Freshwater Wonder Where Nature, History, and River Recreation Meet
Giant Springs is one of the largest freshwater springs in the United States and one of Montana’s most memorable natural landmarks. Serving as the headwaters of the Roe River, the spring flows only about 200 feet before joining the Missouri River, creating a unique and beautiful destination where clear water, river scenery, and outdoor recreation come together.
Discovered by the Lewis and Clark Expedition in 1805, Giant Springs flows from the Madison Aquifer at an astonishing rate of approximately 156 million gallons per day. The water begins in the Little Belt Mountains and travels for roughly 26 years before emerging at the springs, maintaining a constant temperature of 54 degrees Fahrenheit year-round.
Today, Giant Springs State Park welcomes hundreds of thousands of visitors each year. Spanning more than 4,500 acres along the north and south shores of the Missouri River, the park offers trails, fishing, biking, birdwatching, picnic areas, scenic overlooks, waterfalls, a trout hatchery, and access to nearby Lewis and Clark interpretive experiences.

Springs, Rivers & Natural Beauty
Giant Springs is a remarkable display of Montana’s freshwater systems. Flowing from the Madison Aquifer, the spring’s crystal-clear water remains 54 degrees throughout the year. In winter, the contrast between cold air and spring water creates vapor that can coat nearby trees in sparkling ice, giving the park a magical seasonal atmosphere.
Lewis and Clark History
The area surrounding Giant Springs is deeply connected to the Lewis and Clark Expedition, which encountered the springs in 1805. Nearby, the Lewis and Clark National Historic Trail Interpretive Center offers exhibits and educational experiences that explain the expedition’s journey, the importance of the Missouri River, and the broader history of the region.
