Llanwrtyd Wells Cottages
With a population of just over 600, Llanwrtyd claims to be the smallest town in Britain. Situated south-west of Builth Wells, it was once a spa town following the discovery of waters with healing properties in the C18th but today it is famous for a number of weird and original events including the World Bog Snorkelling Championship, the Man versus Horse Marathon and the Real Ale Ramble - to name just a few.
The town has a station on the Heart of Wales line with single coach trains winding their way north-east through the hills to Llandrindod Wells, Knighton, Builth Wells and onto Shrewsbury and south west to Llandovery, Llangadog and Llandeilo before continuing onto Llanelli and Swansea. The line makes for a wonderful day trip; there are four trains a day each way (two on Sunday).
