If you are going down K7000, definitely take the detour to see Grosvenor Arch. It is a five min flat walk, and the arch is spectacular. Walk all the way underneath, on a clear blue day your pictures will be awesome. There is a small parking lot, and a toilet as well. If you are not going down K7000 road anyway, know that this is a 30 mile very bumpy twisty unpaved ride. Perhaps there are other lovely places you can go in the time you'll drive to the arch and back.
