You can’t possibly miss the headland that it’s on but there is a map at the car park to be on the safe side. Very difficult to reach (though a peach compared to the Broch of Borwick). Even to get there you have to go over fractured stone pavement along the coast, pass over a small stream and around a tricky boggy path. Only one of the defensive walls is that obvious but it is charming even if not a full line of stones know. There are some structures o the top that were (?fancifully) called sailors’ graves. I saw one of these by the cliff edge ahead of the stone cairn and on the RH side, roughly 3m across. Just three slabs sticking up and a few other stones beside, but a very obvious structure in regards to the situation
