The Stillwater River comes down from the Beartooth Mountains through a canyon of increasing drama, passing the Stillwater Mine (the only platinum and palladium mine in the Western Hemisphere) before settling into the valley at Absarokee and flowing northwest to Columbus, where it joins the Yellowstone.
The river is excellent trout water from top to bottom. The canyon is extraordinary. The Grizzly Bar in Roscoe — a legendary Montana roadhouse 25 miles south of Columbus — serves steaks the size of serving platters and has done so for decades. None of this is well publicized.
TL;DR
- Columbus (~2,000) is the county seat of Stillwater County on I-90, 40 miles west of Billings at the confluence of the Stillwater and Yellowstone Rivers.
- The Stillwater River is one of south-central Montana’s finest trout streams — accessible from Columbus south into the Beartooth Mountains.
- The Stillwater Mine (palladium and platinum, 40 miles south) is the only mine of its kind in the Western Hemisphere.
- The Grizzly Bar & Grill in Roscoe (25 miles south) is one of the most beloved local restaurants in south-central Montana.
- Best for: Stillwater River anglers, Beartooth Highway access from the north, I-90 road trippers, and travelers who want genuine south-central Montana ranch character.

What Makes Columbus Different
Columbus grew as a railroad supply town and agricultural center in the 1880s, and its economy has been shaped by those dual forces ever since.
The Stillwater River valley runs south from here into progressively more dramatic mountain terrain — the canyon walls rising, the river clarifying, until you’re in genuine Beartooth foothills country near Absarokee and Fishtail.
The Stillwater Mine context is fascinating. The Beartooth Mountains contain some of the oldest exposed rock on Earth (3.2 billion years, among the oldest on the continent) and one of the world’s only economically viable platinum-group-element deposits outside South Africa and Russia.
The mine has operated since 1987, producing palladium and platinum for catalytic converters and industrial applications. It employs several hundred people in a remote mountain canyon. You can see the access road driving through the canyon.
Most travelers know Columbus only as the I-90 exit before Billings. The Stillwater River corridor is worth far more attention than that exit suggests.

The Top 10 Things to Do In & Around Columbus
1. Fly Fish the Stillwater River
The Stillwater is classified as Blue Ribbon trout water — cutthroat, rainbow, and brown trout in a river with excellent public access and moderate fishing pressure compared to more famous streams. The upper river (above Absarokee toward Fishtail) is the most productive for cutthroat; the lower sections near Columbus tend toward brown trout. Multiple fishing access sites along MT-78.
2. Drive the Stillwater Canyon
MT-78 south from Columbus through Absarokee and on toward Fishtail and Nye gives one of south-central Montana’s most scenic canyon drives. The canyon walls close in progressively as you head south, and the geology becomes increasingly dramatic. Turn around at Nye if you’re doing it as a day drive; continue to the Beartooth trailheads if you’re heading into the mountains.
3. The Grizzly Bar & Grill (Roscoe, 25 miles south)
The Grizzly Bar is a Montana legend. A roadhouse in the tiny community of Roscoe serving enormous steaks (the ribeye is the move), cold beer, and old-school Montana hospitality. The dining room fills with ranchers, miners, and out-of-staters who’ve been told by locals to go there. Worth a dedicated trip. Arrive early; they fill on summer weekends.
4. Absarokee (13 miles south on MT-78)
A small, genuine ranching community in the Stillwater Valley — the starting point for serious river fishing and the closest community to the Beartooth foothills. Absarokee has good fly fishing access sites and the character of an unselfconscious Montana small town.
5. Stillwater Mine Overlook (40 miles south, via Nye Road)
The Stillwater Mine access road passes near overlooks of the canyon where palladium and platinum have been mined since 1987. The mine is not open to the public, but the approach road through the narrowing canyon and the scale of the operation visible from public vantage points is striking.
6. Hike in the Absaroka-Beartooth Wilderness
Multiple trailheads in the Stillwater Valley access the Absaroka-Beartooth Wilderness — the same wilderness complex that contains the Beartooth Mountains and some of the most rugged terrain in Montana. The wilderness begins roughly south of Fishtail.
7. Yellowstone River Access (Columbus vicinity)
The Yellowstone runs just north of Columbus — good walleye and catfish fishing at fishing access sites between Columbus and Laurel.
8. Stillwater County Museum
A compact regional history museum in Columbus covering the valley’s ranching, mining, and railroad heritage. Worth an hour.
9. Day Trip to Red Lodge & Beartooth Highway
The most scenic route from Columbus to Red Lodge goes south on MT-78 through Absarokee and Roscoe to Red Lodge — about 1.5 hours but spectacular. From Red Lodge, the Beartooth Highway climbs to 10,947 feet. See Red Lodge guide.
10. Natural Bridge State Monument (via Roscoe/Fishtail area)
A natural stone arch carved by the Boulder River about 60 miles from Columbus via MT-78 and MT-298 — the river flows through and over the arch. A 2-mile round-trip walk from the trailhead.

When to Visit
Summer (June–August): Peak Stillwater River fishing (particularly June for runoff into clearing conditions), full canyon drive access, Grizzly Bar at full season.
Fall (September–October): Excellent brown trout fishing as they move toward spawn, elk hunting season, ranch-country character at its most genuine.
Spring (April–May): Runoff can make the river unfishable but the canyon drive is spectacular; wildflowers in the lower valley.
Winter: Cold; the Stillwater Canyon is beautiful in snow but roads can be icy. The Grizzly Bar stays open.
Personal Tips
Go to the Grizzly Bar. Full stop. It’s 25 minutes from Columbus on a beautiful canyon road. Order the ribeye. This is the meal.
MT-78 to Red Lodge is a better drive than I-90 to US-212. It takes 30 extra minutes but the Roscoe-Absarokee canyon is dramatically better scenery.
The Stillwater River fishes best in September. The June runoff clears by mid-summer, but September — brown trout moving, lower water, clear conditions — is the peak month for serious fishing.
Absarokee has better fishing access than Columbus itself. Drive south 13 miles for the better trout water.

Conclusion
Columbus is a gateway that most travelers use without knowing it — the I-90 exit before Billings, the turning point for the Beartooth, the mouth of the Stillwater canyon. What lies south of that exit is worth far more attention: excellent fly fishing, extraordinary canyon scenery, the remarkable geological context of the Beartooth Mountains, and one of Montana’s best roadhouses 25 miles up the canyon. Come for the Grizzly Bar; stay for the river.

As an I-90 stop and Beartooth gateway, it significantly outperforms most highway-exit towns.
What is the Stillwater Mine near Columbus?
The Stillwater Mine, approximately 40 miles south of Columbus in the Beartooth Mountains, is the only platinum and palladium mine in the Western Hemisphere — and one of only a handful in the world. The mine has operated since 1987, producing these rare platinum-group metals (used primarily in catalytic converters) from an ancient geological formation in the Beartooth Mountains.
What is the Grizzly Bar in Roscoe?
The Grizzly Bar & Grill is a legendary Montana roadhouse in the tiny community of Roscoe, 25 miles south of Columbus on MT-78. Known for enormous steaks, cold beer, and authentic ranch-country hospitality, it’s one of the most beloved local restaurants in south-central Montana and worth a dedicated trip from Columbus or beyond.
Is the Stillwater River good for fly fishing near Columbus?
Yes — the Stillwater River is classified as Montana Blue Ribbon trout water, with excellent cutthroat, rainbow, and brown trout fishing from Columbus south into the Beartooth foothills. Multiple public fishing access sites along MT-78 provide free river access. September is generally the best month for brown trout.
How far is Columbus from Red Lodge and the Beartooth Highway?
Columbus is approximately 65 miles from Red Lodge via the scenic MT-78 route through Absarokee and Roscoe — about 1.5 hours of canyon driving. The scenic route is significantly more beautiful than the I-90/US-212 alternative. Red Lodge is the launch point for the Beartooth Highway.
