Why travel by train from London to Swansea?

Leaving London behind for a few days? Swansea gives you city attractions and the Welsh coast all in one trip.

  • Spend some time by the water - Swansea Bay stretches along the edge of the city, with the marina, promenade and seafront all within easy reach. For a longer coastal day out, head out towards Mumbles or the Gower Peninsula.
  • See another side of Welsh history - The National Waterfront Museum tells the story of industry and innovation in Wales, while Swansea’s connection with Dylan Thomas is still easily traceable across the city.
  • Stop by Swansea Market - Wales’ largest indoor market is a good place to pick up local produce, grab lunch or try Welsh favourites including laverbread and Welsh cakes.
  • Make time for the Gower - Just beyond Swansea, the Gower Peninsula became the UK’s first designated Area of Outstanding Natural Beauty in 1956 and is now recognised as a National Landscape.
  • Head to Mumbles - Independent shops, cafés, coastal walks and its Victorian pier make Mumbles an easy addition to a Swansea break.
