The cache is in a 2 litre transparent sandwich box. Locating the cache should not lead to personal injury - there is no need to crawl/walk through holly bushes (go around the back of them).
I found it difficult to get an accurate position fix because of the tree cover, so be prepared to have a good look around.
There is a car park at N51°25.171 W01°11.723.
