Visit the Countryside Perthshire Big Tree Country Crieff & Strathearn Glen Lednock This picturesque 4-mile (6 km) circular walk follows a waymarked route through mixed and conifer woods with dramatic waterfalls along the way. The route passes by the Wee Cauldron, which is a taster for the much larger pothole known as the Deil’s Cauldron (Devil’s Kettle). Formed at the end of the last Ice Age, this impressive feature has a viewing platform which allows you to safely view the falls that created it. For more information, click here. Lady Mary's Walk The path provides a peaceful stroll beside the picturesque River Earn along an avenue of mature oak, beech, lime and sweet chestnut. A favourite of Lady Mary Murray, the path was opened to the people of Crieff in 1825. For more information, click here. The Knock Take a wander up to the breathtaking viewpoint at the summit of the Knock with views to the Highlands to the north; Upper Strathearn, Ben Vorlich and Comrie to the west; and Muthill, the broad fertile valley floor and the Ochil Hills to the south. On the way up visit Kate McNiven's Crag, where a 17th century witch is said to have been executed by being rolled down the rocky slope in a barrel. For more information, click here.
