Selway River Road
Idaho's longest wilderness access road
The Selway River Road (Forest Service Road 223) cuts through the heart of the largest roadless area in the lower 48, following the crystalline Selway River from Lowell to its headwaters near the Montana border. This legendary route threads between towering Ponderosa pines and granite walls, passing through O’Hara Bar and Race Creek, where mining camps once thrived and remnants of gold dredges still rust in quiet eddies. The road crosses dozens of tributaries on one-lane bridges, each crossing a reminder of how remote this country really is.
Moderate difficulty with seasonal closures from November through May due to snow and washouts. High-clearance 4WD recommended, especially beyond Selway Falls where the road narrows and rocky sections increase. Cell service is nonexistent, fuel up in Lowell, and pack extra water despite river proximity. Dispersed camping is excellent along the entire route, particularly at O’Hara Bar and Three Links Creek. This is Idaho wilderness at its rawest—no crowds, no cell towers, just the sound of moving water and country that hasn’t changed in a century.

Frequently asked questions
Can a stock Tacoma or 4Runner handle the Selway River Road, or do I need a lifted rig?
A stock high-clearance 4WD like a Tacoma or 4Runner handles this road fine under normal conditions. Lockers and a lift help after storms or early season when the road gets rutted and soft, but they're not required. Skid plates are worth having given the rocky sections near the river.
When does the Selway River Road actually open, and can you drive it in early June?
The road typically opens late May to mid-June depending on snowpack and spring flooding — the Nez Perce-Clearwater NF posts current road conditions and closures at fs.usda.gov. Early June can be dicey with high water and road washouts, especially in the middle sections. July through September is the sweet spot.
Do you need a permit to drive or camp on the Selway River Road?
No permit is required to drive the road or use dispersed campsites along it. Campfire restrictions apply during dry summers — check with the Moose Creek Ranger District before you go. The Selway-Bitterroot Wilderness borders the route but driving and camping along the road corridor doesn't require wilderness permits.
What's the hardest part of the drive and what actually makes it challenging?
The roughest sections run through the middle stretch between the Selway Falls area and Magruder Corridor junction — narrow shelf road, loose rock, and tight turns with no guardrails above the river. It's not technically extreme, but the exposure and remoteness raise the stakes; a breakdown or flat here means you're a long way from help. Drive it slow and keep your tires in good shape.
Is there any cell service on the Selway River Road, and how far is the nearest gas?
Zero cell service for essentially the entire 100 miles — plan accordingly and carry a satellite communicator. Fuel up in Lowell before you start; there's no gas until you exit the other end near Darby, Montana, roughly 100+ miles away. Carry extra fuel if your rig drinks more than average.
