Rules in force · 10Non-EU visitors get 90 days in any rolling 180-day window…HSL trams, metro, trains and ferries need a valid ticket …
- Europe ↗Non-EU visitors get 90 days in any rolling 180-day window, counted across all 29 Schengen states together — not per country; the Entry/Exit System now logs each crossing, so an overstay is detected automatically.
- Europe ↗On the first Schengen entry since EES began, non-EU travellers give four fingerprints and a face photo at the border instead of a passport stamp; there is nothing to apply for or pay in advance.
- Nordic countries ↗Decide light or dark before anything else: summer trips (June–August) and aurora trips (September–March in the Arctic) need different countries, clothes and bases.
- Nordic countries ↗Sweden, Norway, Finland, Iceland and the Faroes sell stronger alcohol only in state shops with short hours; buy before evening and before Sundays and holidays.
- 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.

Rescue anchors
A rescue anchor is a spot where you can stop and recover if the walk goes wrong: a bench, a café, a toilet. Every letter on the map is one anchor, and each has a card below. We check that any point in the cluster is within about 7 minutes’ walk of one, so you are never far from somewhere to sit down.
Lettered circles: rescue anchors (green works in any conditions, amber only on hot days). Dashed outline: the cluster. Red dots: spots more than 7 min from any anchor. Drag to move; click the map, then scroll to zoom.
