The Legendary South Fork of the Snake
Swan Valley, Idaho is home to one of the West’s most respected dry-fly fisheries — just minutes from River Retreat Lodge. Guided floats and seasonal walk-in access place guests within reach of legendary wild trout water.
In its clear mountain currents swim Yellowstone cutthroat, wild browns, rainbows, and mountain whitefish creating rewarding days on one of Idaho’s most storied rivers.
Exlusive Private Waters on the Salt River
Select stretches of the Salt River in nearby Western Wyoming are reserved exclusively for lodge guests seeking solitude and unshared access. Fed by high mountain springs, these private waters offer a clear, cold fishery beyond
the public riverbanks — arranged in advance.
Summer days bring animated Western cutthroat to the surface, while early fall offers the chance at larger native browns in these secluded reaches.
Adventure Beyond the River
Wildlife photography at first light.
Hike the renowned Palisades Creek Trail — just minutes from the lodge.
Explore the historic Palisades Reservoir by boat, paddleboard, or shoreline stroll.
Witness elk, moose, and migrating birds and the iconic
Trumpeter Swan in their natural habitat.
And under vast Western skies, experience true mountain wilderness solitude— far from crowds, close to wonder.
Your Swan Valley extraordinary experience begins here.
