I can think of several scenic tours you might enjoy. The Cascade Lakes Scenic Byway is a great choice — lakes, mountains and lots of beautiful forest. Take Highway 26 east through Prineville to the Ochocos — another great backroad through forests. Old McKenzie Highway, Highway 242, is amazing, as is the Aufderheide, Scenic Highway 19. A trip to Crater Lake would be well worth the time, too. Have a great trip!
