A number of Geological Conservation Review sites have been identified within the national park, about half of which have been designated as sites of special scientific interest (SSSIs). The Falls of Dochart, the delta of the River Balvag (Loch Lubnaig Marshes) and the River Endrick have all been notified as SSSIs for their fluvial geomorphology whilst mass movement sites at Ben Vane, Glen Ample and Beinn Arthur (The Cobbler) have been declared GCR sites but not notified as SSSIs. Other Quaternary sites include Croftamie, Portnellan-Ross Priory-Claddochside and the Menteith moraine which is partly within Flanders Moss SSSI. Igneous GCRs include Balmaha & Arrochymore Point (as Conic Hill SSSI) and Garabal Hill. Tyndrum Main Mine and Crom Allt have been designated for their mineralogy, the latter is also an SSSI.
