This cache can be found at the ruin on the beach at Muckle roe. Park at the end of the road into Muckle roe at the car park, and come through the gate past the last house and walk the path until the beach. The ruin on the beach is where you'll find this tiny white cache. Staring North, check the left hand inner corner of the ruined wall, it's hiding in there somewhere! No bigger than an apple. You will be able to see wind turbines in the distance
