Catch the narrow gauge train to the end of Llyn Padarn to start your swim for a truly unique experience! With the spectacular backdrop of the Snowdon mountain range, the historic Dolbadarn Castle and Welsh slate quarries, you can choose to swim the length of the lake once, twice or three times! We have a mid length option too, which is also open to children as young as 8!

The BIG Welsh Swim will take place in Llyn Padarn, Padarn Country Park, Llanberis, Snowdonia National Park, North Wales. The lake is surrounded by some of Snowdonia’s most stunning scenery including beautiful woodland, a historic castle, the old slate quarries that tower above the valley, and the small narrow gauge railway that we’ll use to transport you to the end of the lake! Four distance options: 1.3km, 3km, 6km and 9km.
