North Fork Umatilla Wilderness

Instead of rising into high peaks, to offer a somewhat unique Wilderness experience the gently sloping hills of North Fork Umatilla Wilderness fall into extremely steep, timbered canyons below a high plateau. Down along the river you'll probably feel more isolated than the small acreage of the area would indicate. Vegetation ranges from juniper, sagebrush, and ponderosa pine to fir, spruce, lodgepole pine, and western larch. The North Fork Umatilla River supports populations of bull trout as well as runs of anadromous fish, including steelhead, a major force in pushing for designation of this area as well as an attraction to anglers. However, the river is designated catch and release only.
