Approach notes

Park clear of the gates for the forestry track at the RH side of the crag (as you look from the road). Follow the track until it turns right at which point there is a path on the left which you can follow up to the tree line in about 10 mins. From here, either turn left and follow a faint sheep trail for ten minutes until you reach the obvious big square 50 shades boulder which can be seen from the roadside, or continue right for a few minutes until you reach the biggest concentration of boulders. Castle Grayskull is the gully at the top of this, or continue on the path for 1 minute until it starts to round the hill and you can find the neighbouring Gray's Anatomy sector up the next gully.
