Onich Shore is a classic east-west cross-section through folded Dalradian metasediments, part of the Appin Syncline, including Appin Phyllite, Limestone and Quartzite, and with Ballachulish Slates, plus some minor basic dykes and intrusive bodies. With easy parking and access at the petrol station in North Ballachulish, it is claimed to be the most visited section of the Grampian Terrane. The shore is mainly of shingle, with some short rocky sections; hence walking boots or wellies are recommended. The Dubh Ghlac (Onich Dry Gorge) lies a further 1,000 metres to the west of the section and a series of other localities are scattered around Loch Leven to the east (some of these localities are of quick and easy access, others less so).
