Cascade County, Great Falls
In a state defined by long, brutal winters, open water is a lifeline. Giant Springs, located on the banks of the Missouri River near Great Falls, discharges over one hundred and fifty million gallons of water a day at a constant temperature of fifty-four degrees. When the surrounding lakes and reservoirs are locked in ice, this short, warm stretch of the Roe River remains open, creating a microclimate that draws wintering birds from across the region.
The steam rising from the water on a sub-zero morning obscures the shapes of Common Goldeneyes, Buffleheads, and Greater Scaup diving for aquatic invertebrates. Belted Kingfishers, which would otherwise be forced south by the freeze, rattle along the banks. In the tall, old cottonwoods that shade the park, Great Horned Owls roost quietly through the daylight hours. During the spring and fall migrations, the park serves as a resting point for Common Loons and American White Pelicans navigating the Missouri River corridor.
Visitor Access
Managed by Montana Fish, Wildlife & Parks, Giant Springs is open year-round from 8:00 AM to sunset. Entry is free for Montana residents who have paid the state parks fee with their vehicle registration; non-residents pay an $8 vehicle fee. The park features paved, accessible walking paths that follow the springs and the Missouri River, making it one of the most physically accessible birding locations in the state. No camping is available on site.
