"If you fantasise about turning a few laps in the sightline of a presidential palace or in the shadow of a cruise ship, then head to Allas Sea Pool. This contemporary outdoor construction floats in the harbour directly in front of Kauppatori. Visitors can choose between three pools: sea water (using filtered water pumped in from beyond the harbour); children’s; and a main lap pool, which is heated year-round. Even when air temperatures plunge below zero and the sea is caked in ice you’ll find Helsinkians plying up and down in the steam. The daily entrance fee includes access to the sauna and other facilities."

A "stylish", "modern" marine spa in a prime location, great for photos, but the comfort level falls short. Only three outdoor saunas, small and packed in the late afternoon. The outdoor areas lack any shelter or storage for towels and belongings in rain. The changing rooms are tiny, poorly cleaned, and get slippery – honestly, I found them quite unsafe. Staff are polite and professional, but completely passive: you have to ask, because no info is offered of their own accord. Overall, a slick concept, but maintenance and service feel underwhelming.

Dared Myself To Visit. Glad I Did. Bring a Proper Attitude, it Gets A Bit Nippy Outdoors. Place is Spacious, Came on a Weekday and It Was Just Enough Busy to Feel Comfortable. Outdoor Pool is Great For Laps. Cold Plunge is Exhilarating. Saunas Provide Just Enough Release and Random Nooks and Spots to Relaxe Offer A Relaxing Environment. Would Gladly Come Back Again. Group Friendly. Would Visit Again. There is some construction outdoors but it didn't lessen the experience. 💯 This is a locals favorite.

Don’t skip the sauna experience if you’re visiting Helsinki! This one has three unisex saunas as well as a couple small saunas for just women or just men. The largest sauna has nice sea views through its large window. The smaller, men-only sauna seemed to get warmer, probably because it has capacity of eight and the door didn’t open nearly so often. There are two regular pools for relaxing or swimming, plus a seawater pool for freezing your balls off (yes, it’s that cold even in June). Entrance price varies by day of week (around 20€) and includes three hours of access to pools and saunas as well as a locker (your wristband locks it, no need to bring a lock). Bring your own towel or pay 9€ to rent one. Seriously, I’m glad I brought mine, because I am not joking; it’s 9€ to rent a towel. I left my phone in my locker so I don’t have great photos of the amenities, but here you can see the multiple pools and the changing rooms that house the smaller saunas.

What an experience. Being in such a cold environment but swimming in a heated pool outside. Created a great memory for my son and I. The sea pool was freezing apparently (he went in I didn’t lol) but a novelty for sure. Great saunas and a great time. Would go again.

I loved this sauna, it was a great activity for those who have nothing else to do or visit in helsinki or those who have a bit of free time left. I would recommend going with friends as it's always more interesting. The staff is kind and patient and they also have a little cafe where we tried the croissants (delicious). There are two big saunas for both men and women and then separately a women's sauna and a men's sauna. They also have a big pool for swimming which is regular pool temperature, and then the sea water pool - that one is cold as hell so be parapared to dip in for 5 seconds and leave. Unless you are used to ice baths and stuff like that, it's a whole new experience. I definitely recommend! It might depend at what season you come but we were here in February so it was really cold both outside and in the pool.

We had high hopes for the Finish sauna experience, but we came a little disappointed after spending a couple of hours in the Allas Pool center. The saunas were VERY busy, so much that we had to wait for people to get out before we could get in. Keep in mind they only have 3 coed saunas, so that limited our options. Perhaps it was so busy because it was a Saturday at the beginning of summer. Maybe it would be less crowded during the working week.

Absolutely love this place! Amazing spot for enjoying sauna, sea plunging, and chilling. Now it’s being renovated, so maybe not the best time to visit. Anyway, put it on your “must visit” list!

Nice facility, outdoor heated pool, cold seawater pool, two saunas outside and two more saunas inside near the locker rooms. It costs 18 euros for a two hour session. They have towels for rent for 8 euros. Lockers are provided free of charge!

Beautiful popular spot in Helsinki. There is a great patio, rooftop terrace, and sauna and pool area. The drinks are also good here and it's a fun area to hang out. We moved inside because all the smoking was bothering me but besides that it was a great experience.

I visited Allas Sea Pool while on vacation in Finland, and it was fantastic! I would definitely recommend the experience. Entry to the pool is €12, which I found to be very reasonable. The price gets you an electronic wristband, allowing you entry into all areas (pools and saunas) as well as locker access for a 10 hour period. Re-entry is also allowed, which was extremely useful for me - I was staying a little bit outside of the city, and so I brought a day pack, stashed it in a locker and went to explore the city before returning later in the afternoon to swim. There are three pools which overlook the marina area, so it feels like you're swimming right by the ocean. They are different temperatures, and I believe one is a seawater pool. The pool deck is large and there are a number of deck chairs available for use, however it's also possible to just relax on a towel. Allas additionally has three saunas - male, female and mixed. They are not huge and can fit maybe 15-20 people each, so bear in mind at busy times it could get crowded. A swimming costume is required for the mixed sauna, however in the single sex saunas it is traditional to go in the nude. I believe all saunas are set at the same temperature, therefore there isn't much difference between any of them besides the people. There is also a restaurant and bar onsite, and on the day that I was there, a music festival was running as well, however this was an additional cost not previously included in the entry price. Overall, I'd say Allas is a great place to visit, whether or not you want to swim. Entry is cheap enough that you could go over for a quick dip and also experience Finland's sauna culture, and still get your money's worth. The staff that I encountered were very friendly, and I would definitely return if I ever find myself in Helsinki again!

Pros The breathtaking sauna consept in the heart of Helsinki! Cons: Dressing room is tight; cleaness is bellow average. Huipusti sijaitseva sauna konseptti kaipaa meikki remonttista sekä perus siivousta. Pyyhevuokra 8.5e

Forget Taylor Swift's "Shake it off": here, we (same tune) "Sweat it out"! Allas Sea Pool is right in the Helsinki Harbour, which is amazing if you're visiting the city for just a brief time and want to get in some of the well-known local "sauna culture". Allas Sea Pool is quite a complex: restaurant, upper deck, three pools, saunas, change rooms. Although some regulars seemed to be swimming laps, it's also possible to have a day-only pass (12 Euro) which entitles you to 10 hours of access to all the amenities. There seem to be special events held here, too, such as surf courses and kids' birthdays (I witnessed a clown or three being thrown into the pool). Yelp note: the venue also hosts musical acts - Franz Ferdinand to play soon! - so add some rock 'n roll to your relaxation (R and R and R)!

Great place to hang out in the summer. We visited only for drinks, so this review is not based on the food. Comfy relaxing chairs and good music. There are both seapools and normal swimming pools. Lots of seating options on the roof, by the pools, in the bar area and even in the steps.

This is the only swimming pool that is still open during Covid times in Helsinki. It has a splendid location, facing the Baltic Sea and also near the center. The scenery is quite marvelous no matter it's winter or summer, sunny or moonlight-bathing. The changing room is just a bit crowded and ladies usually have to wait for quite some time to use the hairdryers. But other than that, nothing to complain about at all. Remember to bring your own towers and flip-flops. The price is €15 single ticket and €120 for 10 times.

We didn't actually go in but it looks to be a great place to enjoy sauna and pool. They have also built a really outdoor cool bar/cafe that you can check out a great view without paying for a drink.

Coming to Helsinki, I had to go to a sauna and the Allas Sea Pool has it all at an affordable price. The 12 euros price includes all day entrance to the pools and sauna but be sure to bring your own towel, shampoo and conditioner. There are 3 locker rooms, a mens, women, and coed. You get a wristband that you can use to lock a locker where you store your stuff. Inside the locker room are the showers and a huge sauna. The sauna can definitely fit a good 20 or so people. Once you step outside, there are 3 pools, the freshwater pool, kids pool (closed in the winter), and Baltic sea pool. The pools had a great view of the harbor and you can watch boats come in and out of the harbor. We came during the winter so the freshwater pool was nice and heated while the Baltic sea pool was freezing below 40 degree F. It was a once in a lifetime thing, so we had to jump into the Baltic Sea Pool which we only stayed in for seconds before jumping out. I can see why this is such a popular thing in Finland and I wish this was something we did in the US.

This was a highlight of my stay in Helsinki. The pools was a perfect temperature. The sauna was clean. The cafe was yummy. And the decks and sandy workout area had a perfect view of the harbor. I want to go back to Helsinki just so I can visit Allas Sea Pool again.

Wow. I was in Helsinki for one day and wanted to eat, drink and check out the Sauna lifestyle. After doing a day trip food tour with Heather's Fork in Hand walking tour, she recommended the Allas Sea Pool for the sauna and maybe a swim in the heated pool or sea pool that was currently 0 degrees C or 32 degrees F. It was close to the train station so I was game. I paid a few euro for my ticket and an extra 10E total for the suit and towel rental and went to sauna town. Sauna was fun - did that for 15 min then dipped in the icy cold sea pool...it was amazing.
