Duntulm Castle, once a fortress of the MacDonalds, is an unstable ruin on a dramatic rocky location at the northern end of Trotternish, with views across the Minch to the distant Isle of Lewis. There was possibly an Iron Age fort on the site, it subsequently being fortified by Norsemen, then the MacLeods, whose rivals, the MacDonalds, were in control of by the early 17th century. Duntulm was abandoned in the 18th century. Nearby is a cairn, commemorating the MacArthurs, pipers to the MacDonalds.
Duntulm is accessible with care via a footpath off the A855. Post code is very approximate.
