The caches are all placed close to the forest paths. They are not intended to be hard to find but GPS is notoriously dreadful around here so I have tried to give helpful hints.
You are looking for a clip lock box with space for swaps and trackables.
Placed in accordance with East of England Forestry Commission guidelines. The landowner (Forestry Commission East England) does not assess the suitability or safety of the cache location. The cache placer and the cache finder have a responsibility to take reasonable precautions to protect their own safety and the safety of others. Hazards observed at or on route to the cache location should be reported to the cache placer.
Remember that this is a working forest. Please do not park on verges or block forest access points. Respect any path closures or diversions.
