After seeing to the horses, head back into the wood and then continue N. Pass a huge old spreading chestnut tree, plus a few squelchy bits along here!
At some serious bog a handy boardwalk has been constructed to convey you dry shod across the swamp. Been extended since the cache went out and gets all the way across!
Try not to fall in while looking for the cache! Please search carefully and rehide well. BYOP.
Onwards to a Glorious View.
