A short walk down the now traffic-free old A73 from "Lanarkshire's Coastal Defences", near to Castlehill Bridge.
Unless you have a very full bladder, I strongly suggest that you bring around 2 litres of water with you. Depending on your agility, reinforcements may be near at hand from the Garion Burn.
Please BYOP
(When I placed this cache, GZ was a quiet backwater unfrequented by muggles, duggles or any other type of uggle. It still is, but now looks like a mini builiding site. Next to the cache is a farm track, which I have never known to be used and anyway a permanent fence prevented its use. This has now been torn down and banking excavated out to allow tractor access. From recent tracks, it looks like the farmer has driven some sheep down the track and into nearby gated field. Amazingly, the cache has survived, although it is now in open view. I'll keep my eye on it and may move it slightly. The area is a right mini mess, but hopefully nature will reclaim it and it will become a tranquil corner again.)
