Walk along another section of The Ridgeway where navigation is fairly straight forward.
If you stayed overnight in Ogbourne St. George retrace your steps back onto the Ridgeway trail from your accommodation and carry on following the official path towards Foxhill. After leaving Foxhill there is a left turn shortly aftewards if you are staying in Bishopstone (around 200 metres from Foxhill - or you can walk along a bit further to the Ridgeway Farm and take a left turn onto Idstone Hill Road to reach Bishopstone.) Carrying on along the path you will eventually reach the turn off to Woolstone. If staying in Woolstone you have another 2km walk off the Ridgeway Path to reach your accommodation in Woolstone.
There is some walking on minor roads so please be careful of oncoming traffic.
