Colville National Forest, National forest in northeastern Washington, United States.

Colville National Forest covers 1.5 million acres of the Kettle River and Selkirk ranges in northeastern Washington, within the Columbia Mountains. Its headquarters is in Colville, with ranger district offices in Kettle Falls, Metaline Falls, Newport, Republic and Tonasket. The Salmo-Priest Wilderness lies mostly inside the forest, and the Pacific Northwest National Scenic Trail crosses it, entering through the wilderness and crossing the Pend Oreille River at Boundary Dam.

The forest was placed under federal protection in 1907 to safeguard natural resources and sustainable management. This early conservation decision allowed large areas to remain intact over time.

The Pacific Northwest National Scenic Trail crosses the forest through the Salmo-Priest Wilderness, over the Pend Oreille River at Boundary Dam, past Leadpoint and Northport, then across the Kettle Range to Republic. Camp Growden, the Civilian Conservation Corps' only permanent site in the forest, is kept as a roadside heritage stop between Sherman Pass and Kettle Falls.

The forest provides campgrounds, hiking trails, and fishing areas, with ranger stations available for current condition updates. Visitors should gather information before longer trips as conditions vary with the season.

Large sections of old-growth forest create refuge areas for rare predators like grizzly bears and lynx. These vast untouched zones offer wildlife space that is hard to find elsewhere in the region.
