What makes the Abergavenny area such an important caving site?
In the Abergavenny area, there are 8 caves over 1 km long with a further two close by. Of these 8 caves, Ogof Draenen is the second longest in the UK (with some of the largest passages and many of the best formations), Agen Allwedd is fourth longest, Ogof Daren Cilau is fifth (with the largest passage and many impressive formations), and Ogof Craig A Ffynnon is tenth. Ogof Craig A Ffynnon is considered to be one of the “best decorated caves in the UK”. Eglwys Faen has so many entrances in one area that it should be a record of some kind but it’s probably not. In total, there is over 150 km of known cave within a 15 km radius of Abergavenny.
