The Hermitage, Dunkeld. This stretch of magical Perthshire forest was an 18th-century pleasure ground for the Dukes of Atholl. Giant Douglas firs tower over you as you take the path to the roaring Black Linn waterfall, where the River Braan crashes into the deep, foaming pools below. Deep in the woods, discover the picturesque 18th-century folly known as Ossian’s Hall, which overlooks the stunning waterfall. Cared for by the National Trust for Scotland. | Perth
