Draethen Woods are located between Newport and Caerphilly, to the north of Cardiff. The woods contain a number of lead mining sites and surface workings dating back to at least Roman times. All the sites are fenced off, but there are no known access restrictions. Draethen Woods are located between Newport and Caerphilly, to the north of Cardiff.
