With lunch out of the way, it’s time to experience a particularly Finnish form of relaxation—the sauna. Take a 20-minute cab ride southwest to the former industrial area of Hernesaari, where the newest and most visually stunning example of this integral part of Finnish life, Löyly, has just opened. This oasis of relaxation is a beacon of exceptional modern architectural design. Within, it offers all the pleasurable warmth its name implies (löyly is the Finnish word for the steam that erupts when you throw water on hot stones). For those with an aversion to heat and steam, the restaurant and outdoor terrace provide unencumbered views of the Baltic Sea. Those in search of harder core rejuvenation should try ice swimming—a Finnish tradition that involves plunging into a hole in an icy lake. This invigorating pastime, however, is only available in winter.
