Black Butte is a moderate hike, with phenomenal views of the Central Oregon Cascade range. There is an active fire tower that should be avoided, as the public is not allowed near the tower during fire season. The hike is a 2.1 mile, steady pitch that ascends 1600ft from the parking area. Getting to the trailhead can be done in any passenger car, though the last mile is a bit rough due to a lot of runoff from the heavy snows this past winter. From US Highway 20 turn South on FS-11, then take a left on FS-1110 to the parking area. The route is signed well but the lower section of FS-1110 is gravel and very water boarded so take it easy and plan extra time. Bring extra water, sunscreen and a layer in case the winds pickup or a mountain thunderstorm develops spontaneously. 2M can work if you are patient but its not a bad idea to bring an HF capable radio as well as Central Oregon can be a quiet zone at times.
