Scotland's geosites are chosen because of their local, national or international importance. Take only photos, leave only footprints: avoid causing any damage to this site. You can walk almost anywhere in Scotland without the need to ask permission or keep to paths, but you have a responsibility to care for your own safety, to respect people's privacy and peace of mind and to cause no damage.

Summary
The only reported occurrence of kyanite in the greenschist-facies rocks of the Dalradian of the south-west Grampian Highlands.
This site shows a well-exposed section from the top of the Jura Quartzite to the lower part of the Scarba Conglomerate. The outcrops contain a variety of sedimentary and tectonic structures from which much of the environmental, metamorphic and tectonic history can be deduced. The occurrence of psuedomorphs of kyanite is out-of-sequence in terms of Barrovian zones.
