On the Western side. Directly opposite the lane which takes you down to the SLG bungalow is a large field, beyond which is Barnsley Wold wood. The Western edge of this wood is Barnsley Warren, a site of SSSI. If you look on Google Maps in theory it is easy to spot a number of large trees in the open on the Northern extremities, on of which is the Oak tree. In practice the area is quite overgrown now.
