About Helsinki
Helsinki is the Nordic city people forget about — until they visit and realize it's amazing. Design District has Marimekko and Iittala, the sauna culture is real (Löyly has a public sauna by the sea), and Suomenlinna fortress is a UNESCO site a 15-minute ferry from downtown. Cold, expensive, worth it.
- •Löyly public sauna and sea swimming
- •Design District for Finnish brands
- •Suomenlinna sea fortress (take the ferry)
- •Temppeliaukio Church (built into rock)
