Three Forks Road is a great drive near the Owhyee Canyon Wilderness of Eastern Oregon. This route offers truly amazing views of the Owyhee River Canyon, the best one being the turnout about halfway down the road. There are signs for it; make sure you stop and see it right off the main road.
The gravel road is well-maintained and wide. However, you must watch your speed because there are potholes along the way that can come out of nowhere. And it is an open range, so watch out for livestock on the road.
