On Google maps search for "The Rock, Hillersland" - DO NOT USE THE POSTCODE as it takes you down a narrow, winding road to the wrong house! The Rock is located in Hillersland near Symonds Yat Rock on the road between Christchurch and Symonds Yat. If driving towards Symonds Yat from Christchurch, you will find The Rock on the right just after Folly Lane.
If approaching from the Goodrich turning on the A40, continue past Symonds Yat viewpoint car park. The Rock Lodge accommodation is on the left, keep going for a minute or so and The Rock is a large cream house with a picket fence in front of it and a sign.
