Look up for a 9 trunked tree covered in ivy by the side of the track. You don't need to cross a ditch for this one as the tree is by the track, although you will need to clamber up a small bank to get to the main trunk.
Once found head to the end of this track and follow the signs for Sharpham Road Playing Field.
