This is a bonus cache for those completing the Darnford Moors Ecology Park adventure lab.
At the time of publication, the ecology park had only recently opened, so note that the area is still being developed.
There is room for a car to be parked at the published co-ordinates, but be warned this area is currently very rough ground. Until a proper parking area has been developed at the site, I would recommend using the car park at the given waypoint.
If you are able to complete both this and the Darnford Park adventure lab and bonus cache, GCAR5P9, during the same visit, then you should complete the Darnford Park one first, and then walk down the road to this one.
A link to the adventure lab can be found here
The bonus cache can be found at N 52° 40.AB W 001° 47.CD
You are given the values of A, B, C and D after correctly answering the various adventure lab stages.
