Trackway measuring approximately 160 metres north east to south west. It is situated in a remote field at Mynydd Baedan, approximately a mile and a half north west of Tondu, Bridgend. The trackway is clearly well established, as it is marked on both historic and modern OS maps. The 2017 edition of the OS maps only marks the existence of the trackway using small grey triangles to show its outline. The first and second editions of the 25inch OS maps, however, illustrate trackways that look more extensive than those that appear today, and have labelled them 'intrenchments.' These maps were published in 1877 and 1899 respectively.
