Part of the Brecon Beacons is a UNESCO Global Geopark. This is due to the significant geological formations that can be found there. As part of our Brecon Beacons Ambassador scheme the park geologist takes us up onto areas of the park that are full of these features but quite possibly not that well known as a tourist spot.
Cribarth Geotrail is a good example of this. There is a 3.25 mile walking trail that explores the rocky slopes of the spectacular hill rising above Craig-Y-Nos Country Park in the upper Swansea Valley (Cwm Tawe). The landscape has been carved by water and ice from the folded layers of sandstone and limestone. There are also remains of the quarrying and lime kilns which were such an important part of the 19c industrial landscape.
Aside from all the history there are of cause the views for miles around. To help you get the most from these areas and walks there are detailed leaflets to accompany the trail.
