Head almost to the north of Colonsay on the B8086, then head slightly north west on the minor road, then take the farm track where there is plenty of parking at Kiloran Bay. Spencer would know these roads very well.
Follow the beach north, jump a wee burn, then jump a fence near what could only be the bones of whale and then look north west. The entrance to the cave is in front. Getting there is tricky as it means clambering over rocks and small rock pools.
Once inside, sound seemed to vanish but I kept going until I found the junction of two other chambers, there is a fourth, but at that point the camera decided to stop working, a pity, but I’ll return. Luckily I had my phone as by this point it was completely dark and the idea of getting lost in caves didn’t have much appeal.
Worth another look.
