Loch an Eilein Castle is a beautiful ruined 13th century castle located in Rothiemurchus forest, south of Aviemore. It takes its name from the irregular shaped loch lying beside it. Voted ‘Britain’s Favourite Picnic Spot’ in 2010, make sure you take a camera with you so you have a record of its stunning natural beauty. If you keep your eyes open, you’ll spot some great wildlife here – including red squirrels, ospreys, and crossbills.
