Thermal baths in Portstewart

Portstewart is a seaside town on the Causeway Coast of Northern Ireland, about 7 km north-west of Coleraine. Sauna & Sea parks its wood-fired sauna on Portstewart Strand, the National Trust beach, so a sea dip is a few steps away. The Giant's Causeway, a National Trust site of basalt columns, is about 17 km east along the coast.
