There is a train station in Llandrindod Wells which is on the Heart of Wales line that runs from 121 miles from Shrewsbury to Swansea. It is a very scenic route, passing through glorious countryside and small attractive stations. At these small stations you will need to tell the guard you want to get off or put your hand out if you want to get on! It's a great way to see some of the little towns and attractions along the line, you can stop off and have lunch and then catch the train back. If you are coming from the north you can get connections from Manchester, Crewe and onto Shrewsbury.
