Eilean Donan Castle, Dornie, Scotland. Eilean Donan Castle is one of the most recognised castles in Scotland. It is, without doubt, a Scottish icon and certainly one of the most popular visitor attractions in the Highlands. Strategically located on its own little island, overlooking the Isle of Skye, at the point where three great sea-lochs meet, and surrounded by the majestic splendour of the forested mountains of Kintail, Eilean Donan’s setting is truly breath-taking.
