Just past the church follow the footpath from the stile on your right (very rickety!) and walk parallel to the private road on your left, aiming for the barn ahead (avoid the sheep's droppings!)
Then go over two stiles as you cross another track, with a large barn on your left, over another stile and diagonally across a small field towards the left of a thatched cottage with a conservatory, over the last stile into the road at High Green. Take the right hand road (past the same cottage), pass almshouses on you left. Take the right turn (Cooper Lane - not marked) towards a group of houses out to the junction of the Nowton Road. Find the entrance to the park which you recently used and trace your steps back to the car park.
