The Knock is the wooded hill that rises directly above Crieff's main street, and it is one of those walks that residents take for granted and visitors are delighted by. A network of paths climbs through mixed woodland — mostly mature beech and oak — to the summit at around 290 metres, where the trees thin and the view opens up over the full breadth of Strathearn.
From the top on a clear day the panorama stretches from the flat agricultural plain around Perth to the east, across the Earn valley, and up into the Highland hills to the north and west. It is an excellent introduction to the geography of Perthshire: the sharp line where the lowlands end and the mountains begin is unusually visible from here. Ben Vorlich and Stuc a' Chroin, two prominent Munros, are identifiable to the northwest.
The main path begins near the town centre and takes roughly 30 to 45 minutes at a comfortable pace. The woodland itself is managed and attractive in all seasons — the autumn colour is particularly good. Dogs are welcome and the paths are generally well-maintained. It is the kind of walk that can be done in ordinary shoes in dry conditions, though proper footwear is sensible after rain.
