Scotland is mostly famous for the Loch Ness Monster, Bagpipes, Kilts and Whiskey. We went in 2017, and were stunned by it's nature and beautiful highlands and even mountains. We went hiking, saw cliffs and waterfalls, castles and ruins and of course tried the local whiskey.
Ruthven Barracks in Kingussie is a free well preserved ruin, that you can easily visit if you are in the area. It can even be combined with a hike in the beautiful Scottish Highlands in Cairngorm National Park. Ruthven Barracks is the best preserved of the four barracks built in 1719 by George II's government after the 1715 Jacobite (political movement) rising. It could hold two companies (120 soldiers and their officers).
