The Dylan Thomas Trail is a walking route through some of the legendary Welsh poets favourite parts of Ceredigion and the places that inspired some of his best writing, including Under Milk Wood. Starting in the coastal village of Llanon
the Trail heads inland through mid-Wales farming country to Pennant and after crossing Afon Arth the way follows more country lanes and farmland paths to Cilcennin. From here a country road which is likely to be free of traffic, bar the odd local farm vehicle, to Castell Trefilan. After the castle the hamlet of Tal-sarn is reached. From Pont Tal-sarn road walking ceases when the trail heads back towards the coast by following Afon Aeron downstream. Though the river is parted with at Pont Fawr the coastbound walk continues to the Ceredigion seaside resort of Aberaeron
via Brynog Mansion, Newbridge, Ty Glyn and Llanerchaeron
. From the seaside the coastline is followed south-west to the finish in New Quay (Ceinwydd), via the Ceredigion Coast Path.
