If you're heading from preston it's right outside of town. Head east on Hwy 89 (pretty sure that's it). There is a huge radio tower on the right hand side. Turn right on that road and follow it quite a ways. There will be a 'driveway' plowed out on the right that takes you to the top of a hill. There is a sign on the highway usually, but not always at the driveway. Not as hard as it sounds to get there, really
