You can board the Cambrian Railway train to Shrewsbury. The line runs along the coast of Cardigan bay with spectacular sea views. You can get off at Barmouth or go to Aberdovey and visit these wonderful coastal resorts. A great day out, all for the price of a rail ticket. You can see more about the Cambrian Line on a Channel 5 documentary. Trains also go to Pwllheli from Porthmadog.
