Swim one of the wildest and most breathtaking routes in the UK.

Set in the dramatic Mawddach Estuary in Snowdonia, the swim begins on Barmouth’s sandy beach, sweeps under the iconic railway bridge, and carries you upstream on the fast-flowing incoming tide.

Arrive at The George III in Penmaenpool to steaming hot chocolates, a hearty meal and the unforgettable atmosphere of one of the country’s most beautiful and exhilarating adventure swims.
