Home › Sauna & wellness
Introduction
Warming up in a wooden sauna and then jumping into the sea or a lake with a whoop: in the north it’s simply part of life, for families too. From the city bath in Helsinki to Iceland’s warm lagoons: per country we show places where you’re welcome with kids, with rules and prices from the official websites.
Mind the age rules: they differ from place to place. The Blue Lagoon lets you in from 2 years, the Sky Lagoon only from 12 years.

Per country
In Finland the sauna isn’t a luxury but part of everyday life: many houses and holiday homes have one. As a visitor, the easiest place to start is Helsinki, where you can jump into the Baltic Sea after the sauna.
Location: Hernesaari, Helsinki Type: Public sauna by the sea
Children under 10 years go free and share a parent’s locker; under 18 accompanied. Swimwear is compulsory, and after the sauna you head into the sea. Extra hour 12 €, swimwear rental 8 €.
Location: harbour, Helsinki Type: Pool + 5 saunas
A warm outdoor pool at 27°, a seawater pool and a children’s pool in summer, plus five saunas. Open Mon–Fri 6:30–21:00 and Sat–Sun 8:00–21:00. Ideal if the kids don’t want to stay in the sauna for long yet.
