A guide to the Broadwater Bay swimming area on the Missouri River in Great Falls, MT. Learn about access, safety, and what to expect at this unofficial spot.
Location
Tucked along the storied banks of the Missouri River in the heart of Great Falls, Montana, Broadwater Bay is one of those rare swimming spots that manages to feel both wild and wonderfully accessible. You don't need to drive for hours or hike a rugged trail to reach it — this beloved community gathering place sits right in the city, offering a genuine slice of Montana river life to anyone willing to kick off their shoes and wade in.
The Missouri River here is broad and unhurried, reflecting the wide-open skies that Big Sky Country is famous for. At Broadwater Bay, a sandy beach lines the water's edge, giving the spot a surprisingly beachy feel for a landlocked river town. Cottonwood trees rustle overhead, and if you scan the water or the trees along the opposite bank, you're likely to spot osprey diving for fish or great blue herons standing like statues at the river's margin. The landscape is quintessentially Montana — expansive, quietly dramatic, and alive with the sounds of moving water and birdsong. Nearby restaurants and shops mean you can grab a meal or a cold drink before or after your swim without ever leaving the neighborhood.
The Missouri River at Broadwater Bay runs with a calm, deliberate current that makes it approachable for swimmers of varying skill levels. A sandy beach entry eases you in gradually, and a dock provides a spot to launch yourself into the deeper water or simply sit with your feet dangling in the cool current. Water temperatures are most inviting from June through August, when warm summer days and longer light make an afternoon swim feel like exactly the right decision. The water carries the characteristic cool clarity of a mountain-fed river — refreshing even on the hottest July afternoon. This is an unofficial swimming area, so come prepared: there are no lifeguards on duty, and facilities are not confirmed. Exercise good judgment in the water, especially with younger swimmers.
Great Falls takes its name from the dramatic series of waterfalls on the Missouri River that Lewis and Clark famously — and laboriously — portaged around during their 1805 expedition. Swimming at Broadwater Bay means dipping into waters that carry centuries of history. The community has embraced this stretch of river as a place to gather, cool off, and connect with the natural world that surrounds the city. It's the kind of spot where locals bring lawn chairs and coolers, kids splash in the shallows, and summer evenings stretch long and golden over the water.
Broadwater Bay is located in Great Falls, Montana, making it one of the most accessible natural swimming spots in the region — no entry fee is required.
