On the outskirts of Dunkeld, the Hermitage is a woodland walk that follows the River Braan. In the 18th century, the dukes of Atholl constructed two follies (a fantasy building) here, Ossian's Cave and the awesome Ossian's Hall, above a spectacular—and noisy—waterfall. (Ossian was a fictional Celtic poet invented by James MacPherson in the 18th century for an era fascinated by the primitive past.) You'll also be in the presence of Britain's tallest tree, a Douglas fir measuring 214 feet.
