Overview

Ochoco National Forest encompasses 850,000 acres of Central Oregon terrain, located north and east of Prineville. The forest is currently open with Stage 1 fire restrictions in effect as of June 16, 2025. Winter range closures are active December 1 through May 1 to protect deer and elk, prohibiting motorized vehicles in designated areas. Recent activity includes the Marks Creek Fire (September 2025) which triggered area closures on the Lookout Mountain Ranger District, though this closure was set to expire October 1, 2025. The forest is actively conducting prescribed burns and fuels treatments in spring and fall for forest health and wildfire prevention. Popular activities include camping, hiking (notably Steins Pillar Trail), rockhounding, fishing, and exploring unique geological formations in the rimrock and canyon country. The forest shares administrative management with Crooked River National Grassland, together totaling about 1 million acres of public land.
