Knockan Crag
Creag a' Chnocain
The core geological trail of the North West Highlands UNESCO Global Geopark, where you can physically touch the Moine Thrust, where old rock sits on top of young rock.
Knockan Crag lies beside the A835 road about 20 kilometres north of Ullapool. It is a national nature reserve and the core highlight of the UNESCO North West Highlands Geopark. Here, the Moine Thrust has pushed much older rock layers over younger ones. Research by 19th-century geologists here changed how people understood mountain building. The unstaffed open-air visitor centre has interactive panels and sculptures. A 2-kilometre geology loop trail (about 1 hour) climbs alongside the rock face, where you can touch the fault line with your own hands and look out over isolated peaks such as Cul Mor and Stac Pollaidh. Entry is free, and it is open year-round.
