Park in the Bald Mountain (Rondaxe Mountain) parking lot on Rondaxe Rd, off Rt 28. The hike to the summit is 1 mile, and it's a pretty easy hike, our kids have been doing it since they could walk. A fire tower at the peak is worth the climb, there is a beautiful view at the top! Once you reach the top, and visit the tower, keep hiking past the tower, you'll be on the old trail, and you'll find "Balancing Rock". Be careful of muggles!
5-14-16 Update: I placed a new ammo box, new log, and new stash of swag in a slightly different location. The old location was too worn away. The new location is about 90' west, so keep following the old path past Balancing Rock to find it's new location. Please please PLEASE re-hide it exactly how you found it so it isn't accidentally found by muggles again.
