Helsinki, Finland's capital, sits on a peninsula jutting into the Baltic. It's a compact, walkable city where the harbour and the city centre are essentially the same place. The low, neoclassical architecture of Senate Square, the covered market halls, the design shops of the Punavuori district, and the ferry terminal for Suomenlinna island fortress are all within easy walking distance of each other.
The city has grown considerably since the 1990s and now has a restaurant and cultural scene that holds its own against other northern European capitals. The population of greater Helsinki is around one million — roughly a fifth of the entire country.
For all its Nordic reserve, Helsinki is genuinely welcoming in summer, when the parks and harbour fill up, the terraces open, and the city shakes off months of dark and cold. In winter it's quieter and greyer, but the Christmas markets, ice-skating rinks, and pervasive sauna culture keep things from feeling bleak.
Helsinki makes an easy base for day trips: Porvoo (50 km east), Espoo and its Nuuksio National Park (20 km west), and Hämeenlinna (100 km north) are all reachable by public transport.
