Geology walk around Craig y Rhiwarth

This walk provides access to rocks exposed in disuses limestone and millstone grit quarries on the southern edge of the Brecon Beacons National Park, between Old Red Sandstone and the coal-bearing rocks. A leaflet by The South Wales Geology Group about the walk is available from the Tourist Information Office in the centre of Brecon.

This map shows the route which I followed in April 2004.
