Pant-y-Llyn at Cernydd Carmel is the only turlough in Britain, a type of seasonal lake found in limestone areas, the other examples of which are in Ireland. Pant-y-Llyn fills to a depth of about {{convert|3|m|0}} each autumn, and remains full until it empties completely into a sink hole the following summer. There are no surface drainage streams.{{cite web|title=Cernydd Carmel|url=http://jncc.defra.gov.uk/protectedsites/sacselection/sac.asp?EUcode=UK0030070|website=Joint Nature Conservation Committee|accessdate=3 November 2017}}
