The remains of Dun Grianan sit on the extremity of a low promontory in Loch Mealt, Trotternish, at NG505653, just opposite the Kilt Rock waterfall. Most of the building was removed a long time ago, with just a metre or so of height left on the north side and only the foundations still intact on the south.
The remains was once used as a sheep fank.
Despite the limited walls, the location is an interesting one and is worth a look if you visiting the Kilt Rock viewpoint. It would have been a good defensive position in its day.
