The cache is not at the listed coordinates.
In order to find the final location of the cache you will need to complete the Beaumont Park Trail Adventure Lab. Once each stage is completed you will be given some of the final coordinates.
It is just a nano, so you will need tweezers! It can be found at:
N53 37.ABC W001 48.DEF
It can be busy at the final location and is near the road so please be careful especially if you are with children. Please rehide the cache so that it is out of sight again.
