King Mountain is located in extreme southwestern Oklahoma 17 miles north of Altus and 45 miles south of Interstate 40. From I-40, take exit 66 at Clinton/State Hwy 183. Drive 45 miles south to the town of Hobart. At Hobart, turn west on state highway 9 for 10.2 miles to the town of Lone Wolf. Just before Lone Wolf, turn south on state highway 44 and drive for 9.5 until you come to a bridge that crosses a small canal. I park just northeast of this bridge. From Dallas/Ft. Worth, take U.S 287 northwest to Vernon, Texas. At Vernon, go north on U.S. 283 to Altus, OK. In Altus, 283 changes to state highway 44. Go 17 miles north of Altus on state highway 44. About a tenth of a mile past the entrance you will arrive at a bridge that crosses a small canal. Park just past this bridge. This is your starting point.
The route mainly consists of following the path of least resistance in a fairly direct line up the western slopes of the Mountain. From your car begin to climb a small ridge that protrudes toward the road. I have found that the easiest route involves the loss of a small amount of elevation at the beginning in order to avoid cliffs or brush. The rest of the climb will trend to the north, taking you over second and third class rock. About 200 feet from the summit the slope levels out slightly, and after a little bit more light scrambling the summit will be attained.
Long pants are a necessity for this hike, and boots are strongly recommended. Bring your camera, as this page would not complain if it contained more pictures, particularly of the route. You will want to bring water if you attempt this during a warmer part of the year. Late fall to early spring is the recommended time of ascent. I was climbing in the area in late May and early June of this year and found everything to be very overgrown.
