Cors Goch National Nature Reserve, a couple of miles west of Carmarthen and near the hamlet of Llanllwch, is one of the few raised bogs in West Wales.
It is a Site of Special Scientific Interest (SSSI).
Formed through the accumulation of the remains of plants, and later on peat, it reaches a depth of 5 metres in some places.
Its various types of wet and dry habitats are home to a wealth of wildlife, from insect-eating intermediate sundews, to buzzards and kestrels.
