Route description
Oregon 31 runs northwest-southeast, but is signed north–south. It is a two-lane rural road for its entire length. The northern terminus of the highway is at an intersection with U.S. Route 97 south of the city of La Pine. From there, the highway heads southeast, passing near the natural attractions of Big Hole, Hole-in-the-Ground, and Fort Rock State Natural Area. The route turns briefly east, passing by Paulina Marsh and Silver Lake and through the community of Silver Lake; it then turns south, goes over Picture Rock Pass, and passes by the Summer Lake Wildlife Area, then through the community of Summer Lake and by the lake of the same name. The road then runs east near the south shore of Summer Lake, then southeast through Paisley.
