It is unclear why the two cairns were built together, but local folklore provides its own interpretations. One tale is that one of the mounds is the burial place of a great chief who owned the surrounding land. Each summer he went on a raiding mission with his men, bringing back gold, cattle and slaves. One summer he did not return when expected, but in the autumn the ships sailed slowly into the bay. The body of the chief was carried ashore on his men's shields to be buried in a huge grave, while in the bay below, his galley was ritually set alight.

Another legend holds that the mounds are built on the site of the last battle between the MacDonalds and the MacLeods, two rival clans in Skye. A thick mist descended during the fighting, resulting in carnage so complete that only women and old men were left to bury the dead. All that could be done was to make two piles of bodies, one for each clan, and cover them with stones.
