Come as you like. It is self-service 24/7, open to everyone. Enjoy total freedom, sea, heat. Still one rule applies: 'Do not be stupid'. Get social with people from all walks of life - well you might not get beaten with the birch branches by Sauli Niinistö, the president of Finland. Dress code to your preference – some nudity most likely to come across.
Bring your sauna drinks, towel, flip-flops, sausages or whatever you wish. It is appreciated if you do cut the firewood needed for your sauna session.
