Quick Answer: Ice swimming (avantouinti in Finnish) is the 300-year-old Finnish ritual of sauna-then-dip in water just above 0°C. The 10 best spots include Helsinki’s Allas Sea Pool, Löyly, Kotiharjun, Sompasauna, and Kuusijärvi in Vantaa; Tampere’s Rauhaniemi Folk Bath; and Lapland’s lakeside resort saunas at Saariselkä, Inari, and Ivalo. Entry costs €8 to €24 depending on facility. The hard rules: always sauna first, never alone, 15 to 30 seconds in the water on the first attempt, wool beanie on the head, no alcohol. The 2026 hook is huge: the Winter Swimming World Championships are in Oulu March 2 to 8, the first time the event returns to Finland in 12 years, aligned with Oulu’s European Capital of Culture 2026 year.
The Wim Hof Method costs $799 for a 10-week certification course in California. A backyard cold-plunge tub for tech-bro biohackers runs $15,000 plus installation. The breathing app is $129 a year. Meanwhile, in Finland, a Tuesday in February: a 67-year-old retired teacher named Marja walks 200 meters from her sauna club, climbs down a wooden ladder into a 1°C hole cut into the frozen lake she has used every winter since the Reagan administration, counts to twenty in Finnish, climbs out, walks back to her sauna, and pays €8 for the privilege. The wellness-industry version of cold-plunge therapy is the most-Americanized possible take on a practice that has been part of weekly Finnish life for three centuries.
This guide is the practical companion to the wellness-industry version. Avantouinti (the Finnish word, literally “ice swimming”) is the ritual of cutting a hole in lake ice, walking down a ladder, and submerging up to the neck in water at roughly 1°C immediately after sauna. Done correctly it is invigorating and surprisingly addictive. Done incorrectly it is dangerous. Most travelers who try it once want to do it again, and the Finnish framing of the activity (relaxation, social, communal) is different enough from the Western wellness-trend framing (endurance, biohack, breathing protocol) that the contrast itself is part of the trip.
2026 is an unusually strong year to plan a Finnish ice-swimming trip. The Winter Swimming World Championships return to Oulu March 2 to 8, the first time the event has been in Finland in 12 years, aligned with Oulu’s selection as European Capital of Culture 2026. The Avantoralli festival in Salo runs February 7 to 8 with country-wide celebration of icy dips. Finland is Lonely Planet’s #1 country in Best in Travel 2026, the country sits near peak of the 11-year solar cycle which makes the avantouinti-plus-aurora pairing in Lapland especially strong, and a wave of new Helsinki public-sauna openings is expanding the city’s avanto inventory through 2026.

The 10 Best Ice Swimming Spots in Finland
Ten facilities across Helsinki, Tampere, Lapland, and central Finland, ordered roughly by accessibility for first-time visitors.
1. Allas Sea Pool (Helsinki)
Allas Sea Pool sits at the edge of Market Square in central Helsinki with a sea-water pool that staff keep open all winter by breaking the ice every few days. Three saunas plus an outdoor heated pool (27°C) plus the unheated Baltic sea-water pool make Allas the most accessible introduction to avantouinti for any first-time visitor. Day pass €15 to €20. Open 7 AM to 9 PM weekdays. Towel rental €4. The warm-pool maintenance closure runs roughly four to five weeks starting April 13 2026, which does not affect the cold pool. Best pick for absolute first-timers: the controlled facility with ladders, anti-slip matting, lifeguards, and other bathers around means almost zero safety risk. Pair with the Senate Square morning loop for a clean half-day Helsinki itinerary.
2. Löyly (Helsinki)
Löyly is the design-forward public sauna on the waterfront at Hernesaari (1.5 km west of central Helsinki), with three saunas inside (one smoke sauna) and a Baltic Sea dip step right out the back. Two-hour session €21 to €24 with advance booking. Mixed-gender, swimsuit required. The whole point is the dip: sauna heat for 8 to 12 minutes, walk straight out the back door, drop directly into the Baltic via the wooden ladder. The on-site restaurant on the upper floor does serious Nordic cooking, which makes Löyly the right pick for travelers who want the dip combined with dinner. The architecture itself (sloped cedar staves designed by Avanto Architects) is the differentiator from the more functional Allas format. Walk in armed with the basic Finnish sauna etiquette and the first löyly hits at minute three.
3. Kotiharjun Sauna (Helsinki)
Kotiharjun in Kallio is the last wood-heated public sauna in Helsinki (operating since 1928), and the avantouinti version is the sidewalk-and-snow ritual where locals walk out the front door, dip into the street-side snow piles, and walk back in. Entry €15. Single-gender, no swimsuit, towel only. The ritual here is different from the structured ladder-into-water format at Allas or Löyly: Kotiharjun is the old-Helsinki tradition of cold rinse in the actual snow rather than submersion in lake or sea, which is a useful introduction to the cold-shock concept without the deep-water commitment. The Kallio neighborhood context (working-class roots, gentrifying into the design scene) gives the experience a different cultural texture than the design-forward waterfront saunas. Best for travelers who want the proper old-Helsinki sauna culture.
4. Sompasauna (Helsinki)
Sompasauna is the volunteer-built, free, 24-hour public sauna on the Kalasatama waterfront, where locals dip directly into the Baltic Sea after the sauna heat. No entry fee, no booking, no schedule. Bring your own firewood for the wood-fired stove (or use the wood other visitors left), towel only, swimsuit required for mixed-gender sessions. The Sompasauna scene is the local-cult-favorite version of avantouinti and runs into the genuine Helsinki sauna culture rather than the tourism-formatted version. The Baltic dip directly off the wooden deck (no ladder, no lifeguard, no facility) is the most authentic version of the experience in Helsinki, with the trade-off that you take more responsibility for your own safety. Best for travelers who have already done one structured avantouinti and want the local version.
5. Kuusijärvi (Vantaa, 20 Minutes from Helsinki)
Kuusijärvi in Vantaa is the traditional electric-sauna-plus-smoke-sauna facility with a lakeside avanto cut into Lake Kuusijärvi every winter. The classic first-avantouinti experience for many travelers: ladders, lit area, anti-slip matting, lifeguard present, lake-water rather than sea-water (slightly less salty, less harsh on the skin). The Vantaa location is a 20-minute drive or bus ride from central Helsinki, which makes Kuusijärvi the workable day-trip option for travelers who want the lake-water version without leaving the Helsinki area. Entry is in the standard €10 to €18 range. The smoke-sauna option is the highlight: a separate session at Kuusijärvi’s smoke-sauna is one of the best entry points to the savusauna ritual outside Lapland.
6. Uunisaari Island Sauna (Helsinki)
Uunisaari is a small island in Helsinki’s South Harbour, reachable by a 5-minute summer-ferry or by walking across the ice in deep winter. The island has a public sauna and a Baltic dip-spot that runs as a community-association facility rather than a commercial operation. The winter access is the differentiator: walking across the frozen sea to the island is part of the experience and gives the avantouinti session a different cultural framing than the in-city options. Entry typically €15 to €20. Best for travelers who want the proper Helsinki-archipelago version of the ritual, and who are visiting in deep winter (January-February) when the ice walk is reliably possible. Pihlajasaari Island offers a similar setup with the summer-only ferry access.
7. Rauhaniemi Folk Bath (Tampere)
Rauhaniemi in Tampere is the open-air sauna with a Lake Näsijärvi avanto, operating year-round at €8 to €10 entry (the cheapest serious avantouinti in Finland). Tampere itself is Finland’s sauna capital with more public saunas per capita than anywhere else in the country, and Rauhaniemi is the locally-beloved Folk Bath that draws regulars from across the city. The lake-water version differs from Helsinki’s salt-water Baltic spots: less harsh on the eyes, easier first cold-shock, slightly faster recovery. Tampere is 90 minutes from Helsinki by train, which makes Rauhaniemi a workable day-trip avantouinti option for travelers who want to combine the visit with Tampere’s broader sauna scene at Kaupinoja and the smaller neighborhood facilities. Best for budget travelers and locals-favorite seekers.
8. Saariselkä-Inari Aurora-Avantouinti Combination (Lapland)
The Saariselkä and Inari resort cluster runs guided “Sauna, Ice Swimming and Northern Lights” experiences that combine two saunas (a 30-person main + an 8-person private), an avanto session, and an aurora viewing all in one structured evening. Sessions run from 5 PM and include hotel transfers from Ivalo or Saariselkä. The pairing of avantouinti with the aurora window is the differentiator: the cold-water shock plus the green sky overhead is a combination only Lapland can deliver. Pricing is in the €80 to €150 range per person depending on operator. Best for travelers already in Lapland for the husky-glass-igloo trip who want to add avantouinti without breaking the trip rhythm, especially during the 2026 solar maximum window when the aurora pairing is strongest.
9. Wilderness Hotel Inari Lakeside Smoke Sauna (Lapland)
Wilderness Hotel Inari has a lakeside smoke sauna directly on the frozen Lake Inari shore, with the avanto cut into the lake itself rather than a fed pool. This is the deep-Lapland version of the ritual: smoke sauna (the older, gentler heat format than electric), large frozen lake (one of the largest in Finland), and the full Sami-region cultural backdrop. Hotel rates run around €200 per night double with breakfast, with the sauna-and-avanto session included for guests. Non-guest day-passes occasionally available depending on staffing. Best for travelers who want the deepest-tradition version of the experience, who are willing to make the deeper-Lapland trip to Inari, and who want to combine with the Sami-owned reindeer farms in the same area.
10. Aurora Village Ivalo Private Sauna and Avanto (Lapland)
Aurora Village in Ivalo offers private cabin saunas with cut-ice avantos alongside the glass-igloo accommodation, which gives the avantouinti experience the private-couple version: your own sauna, your own avanto, your own pace, no shared facility. Pricing is bundled with the cabin night rather than separately ticketed, so the cost is wrapped into the €500 to €700 per night cabin rate. The format is fundamentally different from the public-facility versions at Allas or Löyly: you control the timing, the heat level, and the dip duration entirely, with no social or scheduling pressure. Best for travelers on a honeymoon or anniversary trip who want the private version of the ritual, and who are already paying for a glass-igloo cabin at one of the deep-Lapland properties.
How to Actually Do Avantouinti (The Safety Rules)
The ritual is straightforward but the safety rules are non-negotiable, and skipping any of them turns a meditative cold-water experience into a real medical risk. The water temperature is 1 to 3°C even with a frozen surface, the sauna pre-heat is 80 to 100°C for 10 to 15 minutes minimum, the time in water is 15 to 30 seconds on the first attempt (veterans go 1 to 2 minutes maximum, never longer), and the standard rhythm is 2 to 4 sauna-then-dip cycles per session over 60 to 90 minutes total.
The non-negotiable rules. Sauna first, always. Cold-then-sauna in reverse is for experienced cold-water swimmers only, not first-timers. Never alone. Cold shock can trigger an involuntary gasp reflex that inhales water and becomes a drowning risk if no one is there to help. Wear a wool or fleece beanie on your head (most of your body above the water is your head, and head heat loss is the fastest). Wear neoprene booties or socks; the metal ladder rungs are brutally cold without them. Swimsuit required at public spots; nude swimming is reserved for private cabin saunas with a single-gender session. Never drink alcohol before or during. Hard rule.
Skip avantouinti entirely if you have heart disease, high blood pressure, an active fever, or are pregnant; consult a doctor first if you are unsure. What goes wrong if you do not follow the rules: cold shock causes a hyperventilation gasp in the first 30 seconds (which is why the never-alone rule is hard), arrhythmia can trigger in vulnerable people, ladder slips happen on icy rungs, and overstaying causes fingers and toes to lose dexterity fast (which is why the short-dip rule matters). The Finnish word sisu (grit, perseverance) gets invoked sometimes, but Finns themselves do not frame avantouinti as endurance. The point is relaxation and the cold-shock release into warmth, not how long you can stay in.
The 2026 Hooks Worth Planning Around
The Winter Swimming World Championships return to Oulu March 2 to 8 2026, the first time the event has been in Finland in 12 years. The championships are held at Raatti Beach and the Raatti Sport Centre, aligned with Oulu’s selection as European Capital of Culture 2026. Competitors from 30-plus countries swim in heated and unheated ice-pool conditions. As a spectator event the championships are open to the public with viewing access along the pool edge. For ice-swimming-curious travelers willing to organize the trip around the event, this is the single biggest 2026 hook for the activity.
The Avantoralli festival in Salo (SW Finland) runs February 7 and 8 2026 as a country-wide celebration of icy dips and saunas across the town. Smaller scale than the WSWC but a more festival-vibe day-trip option for travelers who want the social-event format rather than the competitive championship. Salo is 90 minutes by train from Helsinki.
Helsinki is opening new public saunas through 2026 in partnership with Helsinki-Uusimaa Outdoors. The Western Neitsytsaari sauna opens June 24 2026, with Malkasaari and Kotiluoto following later in summer. These are primarily summer-coded (the island accesses are easier in warm months) but they expand the public-sauna inventory for the winter 2026-27 season. The cold-plunge boom globally has globalized avantouinti, and Finland’s tourism authorities have leaned into the contrast: the Visit Finland 2026 campaign tagline “Want to feel amazing in 2026? Try avantouinti.” captures the framing.

Is ice swimming dangerous?
Done correctly it is invigorating and surprisingly safe. Done incorrectly it has real medical risks: cold shock triggers a gasp reflex (drowning risk if alone), arrhythmia can trigger in vulnerable people, ladder slips happen on icy rungs. Non-negotiable safety rules: always sauna first, never alone, 15 to 30 seconds maximum on first attempt, wool beanie on head, neoprene booties on feet, swimsuit required at public spots, no alcohol ever. Skip avantouinti entirely if you have heart disease, high blood pressure, fever, or are pregnant.
What should I wear ice swimming in Finland?
A swimsuit (required at all public facilities), a wool or fleece beanie (the head loses heat fastest), and neoprene booties or socks (the metal ladder rungs are brutally cold without them). Bring a thick towel or two. Most public saunas rent towels for €3 to €5 if you forget. Swap into dry warm clothes immediately after the final dip; bring extra socks and a wool sweater for the post-session warm-up.

Final Thoughts
The ice-swimming session is the single most-Finnish thing you can do in a 60-minute window. Pick a public facility for the first attempt (Allas, Löyly, or Kuusijärvi if you are in Helsinki, Rauhaniemi if you are in Tampere), follow the safety rules, count to twenty in the water, and the post-dip warm-up in the sauna delivers a particular kind of clarity that the wellness-industry version cannot replicate at any price point. Try it once, and most travelers want to do it again before the trip ends.
