Gray Butte Tr852 loop can be ridden in the winter when the ground has had time to dry out. The westside trail surface is a mix of clay and sand and sticks to everything when wet, to the point where riders have to carry their bikes because the tires won't roll. So avoid the Springtime thaw and after rainfall.

Gray Butte Tr852 ascends to the 23mi Cole Loop Tr854, with the 9mi Warner Tr854A as a spur loop.

Cole Loop Tr854 encircles Gray Butte and Warner is relatively flat. Consider using FR7290 (SW Park Ln) as the Cole Loop TH. This is a shared TH with some nearby ORV trails.

If the Ridge Rider trails are not open, the Gray Butte Tr852 can be ridden as a 12mi OAB or lolipop ride from the Burma Road intersection.

Summit and River Trail can be added to a Gray Butte ride, and are a great return to the state park TH.

Note: virtually all of the roads near the trails are merely doubletrack jeep trails. The three-digit 'roads' are little more than hiking trails.

The Crooked River is more of an irrigation waterway than anything else, and can become somewhat stagnant during the dry summer months, with short periods of seasonal whitewater rafting available as well.

Smith Rock State Park is a very popular rock climbing destination. Expect the most crowded trail conditions within the park area.

OR State Park Info. Although this page currently has links to the Deschutes NF, Gray Butte is part of the National Forest Grasslands area, at the edge of the Ochoco NF, so the page will be linked to that trail set once developed.

Directions: US97 to Terrebonne, then turn right on Smith Rock Rd and follow signs to the Park. View Larger Map. No Map?.
