The Yellowstone River anchors it all. As one of the longest free-flowing rivers in the country, it winds through town like a living postcard. Calm stretches invite lazy floats, especially between Blue Creek and Coulson Park, while outfitters help visitors slip into kayaks, canoes or stand-up paddleboards. Drift past cottonwoods, watch for eagles overhead and let the water carry you through Billings’ wild open spaces.

But the Yellowstone doesn’t just meander. Sometimes it surges. Just outside the city, whitewater adventurers discover a more exhilarating side of the mighty waterway. Local rafting companies like Adventure Whitewater and Yellowstone River Adventures guide families and thrill-seekers through splashy Class II and III rapids that churn with just the right mix of fun and challenge. These aren't roaring, heart-stopping gauntlets. Rather they’re joyful, get-soaked, laugh-out-loud kind of runs. Along the way, you’ll pause at sandbars to hunt for agates, listen to stories about the river’s ancient geology and revel in the beauty that surrounds you.

For something quieter but just as breathtaking, venture to Stillwater Creek, a true hidden gem. Flowing through the foothills of the Beartooth Mountains before eventually joining the Yellowstone, Stillwater lives up to its name in spirit, if not always in pace. This creek offers a more intimate paddling and fishing experience, where water dances over smooth stones and bends through lush cottonwood groves. The section near Absarokee is especially popular for tubing and small-scale rafting, as it’s gentler than the Yellowstone but still lively enough to be quite an experience. Anglers love the Stillwater, too, for its clear pools and abundant trout, while families appreciate the quiet picnic pullouts, shallow wading spots and feeling of being far away from everything. It’s the kind of place that whispers adventure instead of shouting it.

Lake Elmo State Park offers a more classic day at the lake, perfect for paddleboards, sunbathing, fishing from the pier or simply letting the kids splash in the designated swim areas. The 64-acre lake sits right inside city limits, making it an easy escape that feels worlds away. Spread out a blanket, toss a frisbee or follow the walking trails that hug the shoreline. When the sun’s out, it’s hard to imagine a better place to spend the afternoon.

And then there’s Oasis Waterpark, the high-energy answer to hot summer days. With splash zones, water slides and Montana’s only WaveSurfer ride, it’s all giggles and cannonballs. 

For those who want to dial up the adventure, Montana Wake Co. offers a chance to wakeboard, tube or surf on nearby lakes. No boat ownership required. Their team provides top-notch gear, instruction, and a driver, so all you have to do is hold on and have fun. It’s an exhilarating, sun-soaked way to spend a day with your group.
