I won't reveal much about the (hopefully) interesting container of this one but I will say that,
1) You MUST bring a bottle of water. You'll only need about 250ml but without the water the cache cannot be found.
2) The cache is camoed with bark, please don't try and get it off because it is supposed to stay on the cache.
3) The cache is secured in place so to open it just pull of the top/cap.
hope you enjoy it.
Also, there are quite a lot of brambles near GZ so wear long trousers. I hid the cache in shorts and ended up with very sore legs!
