This small series is for fun and will take you to another couple of caches to bring you back to the start.
There is a bonus so make a note of the numbers you get and if you just remember Pi it will help. A maths degree is not needed.
Access to the BW is straightforward but after this the path runs alongside some large greenhouses and later through a fairly unused pathway. Shorts are NOT recommended. Footpaths may be muddy and wet in winter.
On a sunny day placing the caches the walk took me about 90 minutes. Some of it is on a quiet road.
All caches are intended to be found though one or two may be a little bit sneaky.
