In a fairly dense part of the forest where everything sounds a little different, especially on a windy day, and where the GPS can have a mind of its own, but there are lots of wee clearings so hopefully you get a clear enough signal - difficulty reflects the GPS not the hide!
This is the kind of place we told spooky stories as we walked, or were as quiet as possible and occasionally saw roe deer running through, and no matter how many cars in the car park you rarely saw a soul...
