Well, more above the rocks actually!
Tayinloan's first geocache is a cute little magneting micro situated in a beautiful area. You can look out across the sea to Gigha and Cara, along the beaches, or even up at the wooded hills. Nearby is a b&b which includes a small shop and diner. This area is used by the ferry service to take people to and from Gigha, and has a car park and public conveniences. Please be stealthy and descreet when hunting for this item, the hint is a good one if there are too many muggles.
