After seeing The b of b thread I thought I'd post this.i travel this route on the road directly under this often its beautiful there is one spot" the bwlch " where you can park walk up the side of the hillside and stand above the planes as they fly at low level below you .It can be quite startling if you are cresting the bwlch as the fly towards you but impressive none the less.
