Having walked around Penrose many times and found nearly all the caches to be had, myself and Team Tamar thought we'd hide one ourselves.
This one is hidden a little way off the path, close to the waters edge, although you won't need to get wet, but watch your footing on the way down.
This is my first hide so I hope everyone enjoys trying to find it and would be welcome of any feedback.
