A cache to replace the second cache I ever set up. That one wasn't a clever one (plastic container hidden under some rocks....), and in an obvious place, so it was muggled. I think this one is more worthy. I've enjoyed planning and setting it up, and it will be the first in a series. Yes, I know the novelty will wear off, once you've cracked your first one, but still, I'm sure you'll agree the hide is a good 'un.
You'll need to take some water, and not for the long walk :-) The hide will re-set itself in a few minutes. Make sure you return the container where it came from.
The concrete slab you see beside the cache is the remains of the siding for one of the four rail tracks that used to be here. Amberley was an important rail head, back in the day. The rails set into the concrete used to carry the mobile cranes to unload heavy freight. The olive grove close by was stock yards. Not far away is another cache that explains more. https://www.geocaching.com/geocache/GC75D1T_the-ghost-of-a-station-past-amberley
There's a fairly obvious clue in the name of this cache.
