Coity Mountain

Coity Mountain is a hill summit between Abertillery and Blaenavon that rises to about 578 meters and shapes the South Wales Valleys landscape with its flat-topped peak. The slopes are covered with grass and rough moorland, with multiple walking routes crossing through and several viewpoints along the way.

The northeastern slopes show remnants of coal mining and form part of the Blaenavon Industrial Landscape, a UNESCO World Heritage Site. These abandoned mining structures still shape the appearance and character of the surrounding hills.

The Dog Stone marks where Carlo the Red Setter died during a hunting accident in 1864. This simple memorial shows how the local community remembered an animal that was part of their daily life.

Several public footpaths cross the slopes and the whole area is designated as access land under the Countryside and Rights of Way Act 2000. Visitors can walk freely, but sturdy shoes are recommended as the terrain is rough and can be slippery depending on the weather.

The mountain stood above the ice during the last ice age and shows no signs of glacial deposit on its slopes. This makes it one of the few peaks in the region that escaped the grinding effects of glaciers.
