Rules in force · 6HSL trams, metro, trains and ferries need a valid ticket …
  • Finland ↗Finland is in the EU and the Schengen area. Check the entry rules for your passport on official sources; the EU's Entry/Exit System registers non-EU visitors at the first Schengen border.
  • Finland ↗The land border with Russia is closed to travellers; do not plan a route across it.
  • Finland ↗Everyman's rights let you walk, camp for a night and pick berries on most land, but not near homes, and not to make fires without permission.
  • Helsinki and the South Coast ↗The Helsinki–Tallinn ferry is a border crossing for many passports: carry your passport or national ID card and check the rules for your citizenship.
  • Helsinki ↗HSL trams, metro, trains and ferries need a valid ticket before you board (the HSL app, a contactless card at a machine or a kiosk ticket); inspectors check on board and fine on the spot.
  • Helsinki ↗Public saunas expect a shower first, and swimwear rules differ by venue and by session (mixed with swimwear, or separate by gender): check the rule for your slot before you book.
