A wood-fired barrel sauna on Porth Eirias beach in Colwyn Bay, with the sea for your cold plunge
Save this place
Casgen is Welsh for barrel, which is exactly what you get here: a wood-fired barrel sauna set just steps from the sea on Porth Eirias beach, by Colwyn Bay’s watersports centre on the promenade. You cool off in the sea between rounds. The sauna runs weekend sessions all year, shared or private, and you book by messaging the team on Instagram or Facebook.
