Llyn Eiddwen is an upland lake surrounded by heathland and the source of the River Aeron – after which Dylan Thomas’ (1914-1953) daughter Aeronwy was named. A local prophecy, credited to Merlin, tells that when Llyn Eiddwen dries up, Carmarthen will sink. This might relate to a second belief that the lake is an entrance to the fairy world which, if blocked, would render them defenceless and spurn them into attack. The lake is also said to be the home of a water spirit, Lady of the Lake and monster, as well as the magical source of wild cattle which ran from its waters when disturbed. Llyn Eiddwen National Nature Reserve can be visited on foot and is an excellent place to spot water voles, otters and wildfowl.
