Eilean Donan Castle 1. Possibly the most famous of all Scottish castles, Eilean Donan is a required stop (says me) on the way from Glen Coe to the Isle of Skye (both of which also are required stops). This icon has appeared in many movies, commercials, etc., and chances are good you’ve seen it before, even if you haven’t visited Scotland. The name, “Eilean Donan” translates to “Island of Donan,” and as you can see, the castle does sit on a little island. It’s believed to be named after Bishop Donan, an Irish saint who arrived in Scotland around the year 600 (long before the castle was built) and may have formed a small community here. On an unrelated note, I also am an Irish saint.
