Custom Fly Fishing Trips
Customize Your Experience
For those looking to do more than scratch the surface, RSO Outfitters’ custom multi-boat, multi-river trips are built to explore the best waters the region has to offer—on your terms. These guided trips are perfect for returning anglers, groups of friends, and family, or anyone who wants to fish multiple rivers over several days with expert guides by their side.
Where We Fish
Each trip is fully customized based on season, water conditions, and your group’s goals. Popular river options include:
-
Bighorn River (Fort Smith, MT) – World-renowned trout fishery with year-round productivity
-
Upper Bighorn River (Thermopolis, WY) – Scenic, lesser-pressured water with outstanding spring and fall fishing
-
Clearwater River System (Kooskia, ID) – Wild winter steelhead in a rugged and remote setting (available Jan–Feb). Book through Anglers Edge Adventures
Other lesser-known creeks and tributaries may be included depending on your trip dates and interests.
What To Expect
Each day is a new float, a new perspective, and a new section of water to explore.
Start your morning streamside or at your lodge, meet our guide and hop into a fully outfitted drift boat. With multiple boats and guides, your group can split up, target different stretches, and reconvene for lunch on the riverbank or a shared dinner that evening.
Expect a mix of techniques—dry flies on calm mornings, nymphing deep runs mid-day, and throwing streamers for aggressive trout or steelhead when conditions are right. Whether you’re covering technical tailwaters or wild freestone stretches, our guides match the day’s strategy to what’s working best.
What To Bring
Montana and Wyoming weather changes quickly. Come prepared with:
-
Breathable waders and boots
-
Layered clothing for variable temps (base, mid, and waterproof outer layers)
-
Polarized sunglasses
-
Hat, gloves (spring/fall), and a buff or neck gaiter
-
Personal dry bag for extra gear, snacks, camera, and water bottle
We provide all essential fishing equipment—rods, reels, flies, and terminal tackle—but feel free to bring your own setup if preferred.
