The Selway River is one of America's original Wild and Scenic rivers, designated in 1968 and flowing through the heart of the Selway-Bitterroot Wilderness. It drops about 7,641 feet over 99 miles, carving a deep, forested canyon that feels untouched by time. Its upper reaches offer legendary remote whitewater with only one permitted launch per day, ensuring outstanding solitude. For RV travelers seeking true wilderness, the Selway delivers crystal-clear waters, star-filled nights, and the chance to disconnect in one of the country's most pristine river corridors.
Best season — Summer through early fall (June–September) provides the most reliable flows and pleasant weather, though runoff conditions vary by year. The river is typically too high and cold in spring for casual visitors, and low water can challenge later-season trips.

On the ground
The Selway River in north-central Idaho is a designated Wild and Scenic river, protected since 1968 as part of the Middle Fork Clearwater system. This 99-mile waterway carves through forested land managed by the U.S. Forest Service, offering a uniquely pristine experience. The river’s steep gradient creates challenging conditions while safeguarding its natural character for future generations.
RV travelers to the Selway region generally focus on enjoying the surrounding national forest lands and views of the river itself. There are no roads directly alongside the Selway; access is primarily for those launching into the demanding whitewater, limited by a single permitted launch each day. The area provides opportunities for hiking and appreciating backcountry solitude.
The best time to visit the Selway is during summer through early fall, from June to September. This period offers more reliable river flows and pleasant weather conditions. Spring runoff typically makes the river too high and cold, while later in the season low water levels can present challenges for those navigating its waters. Conditions vary annually.
Consider establishing a basecamp within the national forest as a starting point for exploring the Selway area. From there, plan day trips to viewpoints or trailheads offering access to the surrounding wilderness. The remote nature of this region requires careful planning and self-sufficiency for RV travelers seeking its unique beauty.
