Bighorn River Fly Fishing Day Trip | 8 Hour Trip
The Bighorn River below Yellowtail Dam is hands down one of Montana's premier fly fishing destinations, and this full-day guided trip puts you right in the heart of the action. At $400 per person with a maximum of two anglers, you're getting an intimate experience on some of the most productive trout water in the West. We're talking about a tailwater fishery that's consistently ranked among the top trout streams in North America – and for good reason. The cold, clear water flowing from Bighorn Lake creates perfect conditions for massive rainbow and brown trout that'll test your skills and make your day.
What to Expect on the Water
Your 8-hour adventure typically kicks off at 8 AM, though we're flexible based on what's working best that day. Sometimes the fish are more active in the afternoon, and we'll adjust accordingly – that's the beauty of fishing with local guides who read the water daily. You'll be floating in a drift boat designed for fly fishing, covering prime stretches where the big fish live. The Bighorn runs crystal clear most of the year, which means you'll often spot your target before you cast. It's technical fishing that rewards precision, but don't worry – our guides know every riffle, pool, and undercut bank where the trout hang out. We provide everything you need: rods, reels, flies, and all the tackle. Plus, you'll get a streamside lunch and drinks to keep you fueled throughout the day. Just remember to grab your Montana fishing license beforehand, and plan on tipping your guide around $100 – they work hard to put you on fish.
Techniques & Tactics
The Bighorn is primarily a nymphing river, though dry fly action can be phenomenal during hatches. Your guide will rig you up with the right flies for conditions – think tiny midges, BWOs, and PMDs depending on the season. We're often fishing size 18-22 flies, which means you'll be working on your precision casting and mending skills. The fish here are educated, so presentation is everything. Your guide might have you indicator nymphing in the deeper runs, swinging soft hackles through the tailouts, or sight fishing to rising trout during a hatch. The water stays fishable year-round thanks to the dam release, but each season brings different opportunities. Spring means big browns on the move, summer brings consistent dry fly action, fall sees the browns getting aggressive before spawn, and winter offers some of the best nymphing of the year when crowds thin out.
Target Species You'll Hook
Rainbow trout are the bread and butter of the Bighorn, and these aren't your average stockers. We're talking wild fish that average 16-18 inches, with plenty of 20+ inch specimens to keep things interesting. These rainbows fight like freight trains – they'll take you into your backing and jump multiple times before you get them to the net. They're most active during the warmer months and absolutely crush dry flies during mayfly hatches. The beauty of Bighorn rainbows is their consistency – you can count on finding them in predictable spots throughout the system.
Brown trout are the crown jewel of the Bighorn, and this river produces some true giants. These fish can reach well over 24 inches and have the attitude to match their size. They're notoriously finicky and prefer deeper water during the day, often tucked under banks or in the slower pools. Fall is prime time for big browns as they become more aggressive before spawning. They'll smash a well-presented streamer or sip tiny midges with equal enthusiasm, but everything has to be perfect. When you hook a big Bighorn brown, you'll know why anglers travel from around the world to fish this water.
Lake trout aren't as common as the rainbows and browns, but they add an element of surprise to your day. These deep-water predators occasionally move into the river system, especially during spring and fall. When you hook into a laker, you're in for a completely different fight – they're bulldogs that use their weight and the current to their advantage. Most lake trout caught in the river are in the 18-24 inch range, though larger specimens are always possible. They typically prefer deeper pools and will often take larger flies or streamers.
