Simple find just off a quiet footpath through the woods. It's a short walk uphill from the recommended parking spot.
The path is usually firm underfoot but it's steep in places and there are plenty of trip hazards. Probably one to avoid for wheelchair users. Sorry.
Should be plenty of cover from passing cars but keep an eye out for passing walkers, cyclists and dogs.
You're looking for a plastic bottle (about the same size as a jam jar) a few feet from the path on the LHS as you go up the path.
