Upper Road, off Castle Hill Road in Dover. Upper road leads to Langdon Cliff. Drive along Upper road and go over the Bridge and shortly after you will see a dirt layby on the left. It is large enough for three cars. Across the road is a signpost to a footpath in the woods. There are lots of places for hidden fun. Just as you walk into the woods, there is a bank on the left. It is not too steep. I love to go down there as there are lots of hidden places for fun. In the summer its even better when the foliage has grown. Very discrete fun to be had.
