Co-ordinates above will take you to the "entrance". The cache is located approximately 15 metres inside, just before the "first room" on the left.
Important Note: If you decide to venture further in, just because you can, please take care.

There is a video on You Tube that shows the search and subsequent find of a cache, be aware that the cache shown in the video is an old container.
Through evolution, high muggle traffic this cache container is about four generations old. The cache does reside within half a metre of the footage shown in the video.
