70 miles of untamed river. 1.3 million acres of wilderness. No crowds. No compromises. Welcome to the Lochsa corridor.
Begin Your Journey ↓Pronounced LOCK-saw, the name comes from the Nez Perce language and means "rough water." It's a fitting name for a river that drops 31 feet per mile through 63 rapids in 64 miles — more than half of them Class IV.
The Lochsa River begins near Powell Ranger Station in the Bitterroot Mountains and flows 70 miles southwest to Lowell, where it meets the Selway River to form the Middle Fork of the Clearwater. US Highway 12 — the Northwest Passage Scenic Byway — parallels the river through one of the most remote paved corridors in the American West.
The corridor winds through the Nez Perce-Clearwater National Forest, harboring an ecosystem found nowhere else on earth — a globally unique intersection of Pacific coastal and Rocky Mountain biotic communities. Elk, moose, black bear, mountain lion, wolves, bald eagles, osprey, and river otters share this landscape with ancient cedar groves, wildflower meadows, and geothermal hot springs.
The remote mountain town of Powell, Idaho — home to the Lochsa Lodge — is the beating heart of the corridor: fuel, food, cabins, and a tavern that's been gathering adventurers since 1929. Beyond that, it's just you, the river, and the mountains.
The Lochsa corridor has been a passage, a home, and a proving ground for as long as humans have walked this continent. These mountains hold stories of Indigenous peoples, starving explorers, doomed hunting parties, and the pioneers who built the American West.
The Nez Perce have inhabited the Clearwater region for at least ten millennia. At the time of Lewis and Clark, they were the largest tribe on the Columbia River Plateau — roughly 6,000 people commanding 17 million acres across Idaho, Oregon, Washington, and Montana.
The Lochsa corridor is recognized as a Traditional Cultural Property — the ancient k'useyne'iskit ("Trail to Buffalo Country") linked the river to a vast network of gathering grounds, fishing holes, and sacred sites. Weippe Prairie, where Clark's advance party first encountered the Nez Perce in September 1805, was a major gathering point for baking camas bulbs. The Nez Perce were instrumental in creating the Appaloosa horse breed through generations of selective breeding.
In 1877, Chief Joseph and approximately 750 Nez Perce fled along the Lolo Trail, covering 1,300 miles over three months before surrendering just 40 miles from the Canadian border — one of the most remarkable and tragic passages in American history.
On September 11, 1805, the Corps of Discovery began the most harrowing leg of their entire expedition — a 120-mile crossing of the Bitterroot Mountains along the ancient Nez Perce trail. They nearly perished. Harsh weather, waist-deep snow, no game. They killed and ate horses to survive.
Starving and disoriented, the expedition was saved by the Nez Perce at Weippe Prairie. On the return trip in 1806, they camped near present-day Kamiah for nearly a month, waiting for the snow to melt. Lewis collected 170 plant specimens new to science. The highway you drive today traces the route they traveled — shown to them by the Nez Perce.
Fur trappers were among the first Euro-Americans in the Lochsa country. Jerry Johnson — the legendary trapper and prospector for whom the famed hot springs are named — kept a cabin along the river. Bud Moore grew up trapping these drainages in the 1920s and went on to spend 40 years with the Forest Service, becoming one of the region's greatest land stewards.
The CCC built the Lolo Motorway along the ridgeline in the 1930s. The first smokejumpers deployed at Martin Creek on the Selway in July 1940. Highway 12 wasn't completed until the early 1960s — making this one of the last sections of the American West to be connected by paved road.
Three New York hunters — led by Will Carlin and Abraham Himmelwright — their guide Spencer, and camp cook George Colegate entered the Bitterroots in September 1893. Record early snows trapped them on the Lochsa. Horses were lost, supplies exhausted. Colegate fell gravely ill.
The party made the controversial decision to leave Colegate behind on the riverbank. Multiple military rescue parties were dispatched from Missoula, Fort Spokane, and Kendrick. The survivors were rescued near Lowell on November 22. Colegate's remains were found the following summer, eight miles downriver. His grave at Colgate Licks along Highway 12 is a somber reminder of these mountains' indifference to human ambition.
The DeVoto Memorial Cedar Grove shelters Western Red Cedars that were ancient when Columbus sailed. The Lolo Motorway still follows the same ridgeline the Nez Perce traveled for millennia. The river still drops 31 feet per mile, untouched by dams. This is a place where history isn't behind glass — it's under your boots.
The Lochsa corridor doesn't have an off-season — it has four distinct worlds, each with its own character, its own silence, and its own way of reminding you why you came.
The Lochsa comes alive. Snowmelt transforms it into one of the West's premier whitewater runs — 63 rapids, Class III-IV+. Peak flows April through June.
Burn scars and moist forest floors produce world-class morels. Daytime temps in the 60s and nights in the 40s are the magic window.
Elk calving, bear emerging from dens, bald eagles returning to nest. The corridor pulses with new life. Colgate Licks mineral springs draw herds at dawn.
Jerry Johnson and Weir Creek hot springs with snow still on the banks. Trails may be icy — but the reward is worth it.
Catch-and-release steelhead season runs through the Friday before Memorial Day. Trophy fish in crystal-clear water.
The landscape awakens with shooting stars, glacier lilies, and trillium carpeting the forest floor along the river.
Westslope cutthroat, rainbow trout, chinook salmon, steelhead, mountain whitefish, bull trout. Dry fly season from June through September in gin-clear water.
Dozens of trails from riverside strolls to wilderness summits. Eagle Mountain, Lochsa Peak, Boulder Creek into the Selway-Bitterroot. Wildflowers peak in July.
July and August bring the wild huckleberry harvest — Idaho's legendary berry. Lolo Pass and the surrounding ridges are prime picking territory.
95 miles of primitive road along the Bitterroot Divide — Lewis & Clark's route, Nez Perce trails, Indian Post Office rock cairns. Accessible July–October. 4WD required.
Multiple outfitters offer guided rides into the Selway-Bitterroot. Boulder Creek, Meadow Creek, and the ridge trails offer backcountry horse access.

Reduced crowds, cooler water, and aggressive fish. Fall is the locals' favorite season on the Lochsa. Cutthroat rise eagerly to dry flies through October.
The fall colors along the Bitterroot Divide are extraordinary. Clear skies, cool temps, and no bugs make September-October the ideal time to drive this historic route.
Summer crowds vanish. The corridor returns to its natural quiet. Morning mist on the river, bugling elk, and the smell of wood smoke — fall is pure Lochsa.
Chanterelles, lobster mushrooms, and late-season boletes. The damp autumn forest floor delivers to those who know where to look.
350+ miles of groomed trails launching from Lolo Pass throughout the Bitterroot and Clearwater ranges. Deep powder, dramatic terrain, and virtually no crowds.
