River Fishing
Full-day guided trip targets rainbow and brown trout.Eight hours on Montana's Bighorn River with expert guides.All equipment, lunch, and shuttle service included.
The Bighorn River isn't just another trout stream – it's the kind of water that turns first-timers into lifelong fly fishing addicts. This tailwater fishery below Yellowtail Dam consistently ranks among Montana's best trout rivers, and for good reason. Our full-day guided trip puts you right in the heart of some of the most productive trout water in the West. With crystal-clear flows, consistent temperatures, and healthy populations of rainbows and browns, the Bighorn delivers the kind of fishing that makes you forget about everything else. We're talking about a river where 18-inch trout are common, 20-inchers show up regularly, and the occasional monster pushing 24 inches will test your drag system.
Your day starts at 8 AM, though we're flexible if you want to sleep in or get an earlier jump on things. This is your trip, and we roll with what works best for you and your fishing partner. At $400 per person for two anglers maximum, you're getting personalized attention that bigger operations just can't match. We keep groups small because that's how you actually learn something and land more fish. Your guide knows every riffle, every undercut bank, and every seasonal holding spot on this 13-mile stretch of world-class water. They'll handle the boat, read the water, and put you on fish while sharing decades of local knowledge. The streamside lunch gives you time to swap stories and gear up for the afternoon bite, which can be absolutely lights-out when conditions align. Don't forget to grab your Montana fishing license before we meet – that's on you, along with any adult beverages you want for after hours and a tip for your guide (standard is $100 per angler for a day like this).
The Bighorn fishes different than your typical freestone river, and that's exactly why it produces such consistent results. We're drifting in comfortable boats, covering water efficiently while working the prime lies where big trout feed. Your guide provides everything – rods, reels, lines, and a fly box full of proven patterns that work on this specific water. Nymphing is the bread and butter here, and we're talking about technical presentations with multiple fly rigs, strike indicators, and just enough weight to get down without spooking fish. When the PMDs or caddis are coming off, we'll switch to dry flies and watch fish rise in water so clear you can see them coming from 20 feet away. Streamer fishing can be absolutely explosive, especially for the bigger brown trout that hunt in the deeper runs and undercut banks. The boat lets us fish water you'd never reach from shore, and your guide knows exactly how to position you for the best drifts. This isn't combat fishing – it's technical, rewarding angling where every cast has potential.
Rainbow trout are the workhorses of the Bighorn River system, and these aren't your average stockers. We're talking about wild rainbows that average 16-18 inches, with shoulders like footballs and attitudes to match. They fight harder than rainbows in most waters, thanks to the constant current and abundant food sources. Spring through fall offers excellent rainbow action, but the pre-runoff period and late fall can be absolutely phenomenal. These fish love the riffles and drop-offs, and when you hook one, get ready for some serious runs and aerial displays. There's nothing quite like watching a 20-inch Bighorn rainbow clear the water three times before you get it to the net.
Brown trout are the ghosts of the system – bigger, smarter, and more selective than their rainbow cousins. The Bighorn browns average larger, with fish in the 18-22 inch range common and legitimate monsters over 24 inches lurking in the deeper pools and structure. These fish have seen every fly pattern known to man, so your guide's local knowledge becomes crucial. Fall is prime time for browns as they feed heavily before winter, but skilled anglers can find them year-round. They prefer the deeper, slower water and undercut banks where they can ambush prey. Landing a big Bighorn brown is like earning a PhD in fly fishing – it requires patience, skill, and a little luck.
Lake trout represent the wild card in your Bighorn experience. While not as common as rainbows and browns, the lake trout in this system can reach impressive sizes and provide a completely different fight. These deep-water predators occasionally move into the river from Bighorn Lake, especially during certain seasonal transitions. When you connect with a lake trout, you're in for a battle that's more about power and endurance than the acrobatic displays of trout. They're the kind of fish that make you check your knots twice and appreciate a good drag system.
River Rock Outfitters has built a reputation on the Bighorn for putting clients on fish while teaching them something about this incredible fishery. This isn't just about catching trout – though you'll do plenty of that – it's about understanding why the Bighorn produces such consistently excellent fishing and how to make the most of your time on world-class water. The 50% deposit locks in your date, and trust me, prime dates fill up fast once word gets out about how the fishing has been. Whether you're a seasoned angler looking to add the Bighorn to your list of conquered waters or someone ready to step up their fly fishing game, this day trip delivers the kind of experience that changes how you think about trout fishing. The combination of expert guiding, top-notch equipment, and access to some of Montana's most productive water makes this a top-rated choice for serious anglers.
Drift the legendary Bighorn River in our custom 2024 Sunburst Driftboat, a beautiful 15-foot wooden craft built specifically for Montana's premier trout waters. This engine-free boat moves silently at 5 MPH, letting you focus on landing rainbow and brown trout without spooking fish in shallow runs. The wooden construction cuts through currents smoothly while keeping noise to a minimum - crucial for success on this technical river. Designed for two anglers, you'll have plenty of casting room and easy access to both bow and stern positions as your guide reads the water and positions the boat over productive lies. The classic drift boat design handles the Bighorn's varying flows perfectly, from deep pools where big browns hide to riffle sections where rainbows feed aggressively. Your guide will anchor in prime spots or let you drift and cast to rising fish, making the most of this world-class fishery during your full 8-hour day on the water.
Tylosurus AcusBrown trout are the wary ones that keep guides on their toes. These golden-brown beauties with black spots typically run 12-20 inches here on the Bighorn, though we see plenty pushing 24+ inches. They love deep pools, undercut banks, and any structure that gives them cover during bright days. Fall and winter are prime time when they're feeding aggressively before and during spawn. Browns are notorious for their powerful runs and stubborn fights - they'll test your drag and patience. The meat is excellent eating with a firm texture. Pro tip: fish the shadows and overhangs during midday heat. Browns often hold tight to cover where other trout won't, so get your fly right against the bank structure.
Salvelinus NamaycushLake trout aren't our primary target on the Bighorn River trips, as they prefer the deep, cold lakes rather than flowing water. These massive char can reach 30+ pounds and live in depths of 60-100+ feet in places like Bighorn Lake. They're slow-growing, long-lived fish that fight with deep, powerful runs rather than flashy jumps. Cold months right after ice-out offer the best shallow water opportunities when they move up to feed. Anglers love them for their size potential and the challenge of fishing deep structure. The white, flaky meat is excellent eating. Since we focus on river fishing, you'd want a dedicated lake trip with downriggers and heavy tackle to properly target these giants in their preferred deep, cold habitat.
Oncorhynchus MykissRainbows are the acrobats of the river, known for those spectacular jumps that get everyone's adrenaline pumping. You'll find them in 12-18 inch range mostly, with some nice 20+ inch fish in the deeper runs and pools. They prefer the faster water - riffles, current seams, and oxygenated flows where they can easily grab drifting insects. Spring through fall offers consistent action, especially during mayfly and caddis hatches. What makes them special is that explosive energy when hooked - they'll leap, run, and fight until they're completely spent. The pink flesh is sweet and flaky when cooked fresh. My go-to technique: watch for rising fish during evening hatches and match whatever's coming off the water.
