Finland offers two outdoor travel treasures that astonish visitors from Japan, East Asia, Europe, and North America: first, a nationwide network of 5,628 public lean-to shelters (laavu), timber grill huts (kota), and unlocked wilderness cabins (autiotupa) that are 100% free (0 €) for anyone—including foreign tourists—to use without reservation; and second, a year-round network of state-funded commuter ferries (yhteysalus) that carry foot passengers and cyclists to remote outer archipelago islands completely free of charge (0 €).
Whether you are arriving in Helsinki for a short stopover, riding the night train to Lapland to watch the Aurora Borealis over a frozen lake, or island-hopping through the Turku and Kotka archipelagos, this guide explains step by step how to use our interactive shelter map (English Map • 日本語マップ / Japanese Map • 中文地图 / Chinese Map) together with our sister island-hopping platform IsleHops.com (日本語版はこちら).

Essential Rules of Finnish Nature (Jokamiehenoikeus) & Shelter Etiquette
- Never Light Open Fires During a Forest Fire Warning (Metsäpalovaroitus): Before lighting any campfire in spring or summer, check the Finnish Meteorological Institute warning map (
en.ilmatieteenlaitos.fi/warnings). When a forest or grass fire warning is active, lighting an open fire is strictly illegal even at official laavu fire rings. Only enclosed chimney stoves or portable camping gas stoves may be used. - Never Cut Living Trees or Strip Birch Bark: Taking bark from living birch trees or snapping branches is illegal. Always use the dry split logs in the shelter's woodshed (puuliiteri), use wood sparingly, and split a handful of kindling (kiehiset) for the next hiker before you leave.
- Always Share the Shelter: You can never "claim" a public laavu or autiotupa exclusively for your group. Greet newcomers warmly and make space on the sleeping platform.
- Pack Out All Trash (Leave No Trace): Wilderness shelters do not have garbage collection. Never throw tin cans, aluminum foil, or plastic wrappers into the fireplace.
