The main access for the Wenaha River Trail is from the Troy Trailhead near Troy, Oregon. With a starting elevation of less than 2,000 feet above sea level, this portion of the trail can be accessible nearly year-round depending on weather conditions.
From the trailhead, it is approximately five miles to the boundary of the Wenaha-Tucannon Wilderness. The trail contours above the Wenaha River, a designated Wild & Scenic River, sometimes hugging the cliffs, and other times coming down to flat benches along the river with access to good campsites. Watch the hillsides for deer, elk, and bighorn sheep, and look overhead for eagles and other birds of prey.
Just inside the Wenaha-Tucannon Wilderness, at approximately the six-mile mark, the trail intersects the Crooked Creek Trail. Although portions of the trail were heavily impacted by the 2015 Grizzly Complex Fire, the forest is beginning to recover nicely. The bridge over Crooked Creek was replaced in late 2023, restoring early season access to the upper reaches of the Wenaha River drainage. The full length of the Wenaha River Trail is 29.9 miles. With numerous intersecting trails, it is possible to create a number of longer loop backpack trips once the snow melts on the higher elevation trails within the Wenaha-Tucannon Wilderness.
