Some climbing required, but anyone with an average level of fitness should be fine, and the views at the end will be worth the effort. 
This fourth and final stop brings you to the top of the cliff (no more climbing required, hurrah!). Stop for a bit, catch your breath, and enjoy the views.
You are looking for a (we hope) well camouflaged 35mm canister.
There is no need to jump over the fence to find it. Please don't go near the cliff's edge!
Although out of sight from the neighbours, you do have to walk right past someone's house, so we wouldn't recommend doing this one after dark as it might look a bit dodgy....
Don't miss out the house in the corner with rather "interesting" garden decorations...
Update 15/07/10: We have improved this cache after finding it just lying on the ground instead of in its intended position, which would make it not just obvious to geocachers (which we don't mind as we know we can only fool you for so long! 
), but to any muggles who may go up that way - and judging by the rubbish found around GZ, it's apparent that some do go there to eat their burgers!
Can you please replace the cache carefully and leave it as you found it, so muggles don't give it a second glance. Cheers!
