If you’re staying in Vienna and want a proper thermal spa day without taking a long trip out of the city, Therme Wien is really your only option, but that also raises the question: is it actually worth it, or just convenient?

I went in a bit sceptical, expecting it to be busy, a bit overpriced, and not quite as relaxing as some other ones.

But after spending a full day there on a quiet Monday in March, I actually really enjoyed it. It was much bigger than I expected and very relaxing.

In this guide, I’ll share my full personal experience at Therme Wien, including what the pools and sauna are really like, how the pricing works (and where it adds up quickly), and what vegan food options you can expect.

By the end, you’ll know exactly whether this thermal spa in Vienna is right for you and how to plan your visit if you decide to go.

Is Therme Wien Worth Visiting?

Short answer: yes, but it depends on what you’re looking for.

If you’re staying in Vienna and want an easy, relaxing spa day, Therme Wien is a great option. It’s much bigger than I expected and really relaxing.

That said, it’s not my favourite thermal spa in Austria. I personally prefer Bad Blumau, which feels more unique, but it’s not as easy to get to from Vienna.

What I liked

Very easy to reach from the city
Large pool area with plenty of choice
Different temperature pools, some are actually nicely warm (I’m very picky about that)
Relaxing atmosphere (especially on weekdays)
Big sauna area (including a women-only section)
The kids area is separate, so you don’t hear it in the main pools

What I didn’t love

It gets expensive quickly, especially since you only pay at the end (there are a lot of add-ons)
Some pools could be warmer
Food is okay but not worth the price
I’ve read it gets very busy on weekends in winter

There are also more premium add-ons like lounge areas, but I skipped those since the standard ticket (plus sauna) was already expensive enough for me.

My honest verdict

If you want a convenient spa day while staying in Vienna, it’s definitely worth it.

Just don’t expect it to be the most unique spa experience in Austria. Think of it more as an easy, relaxing escape within the city, rather than a luxury destination (unless you pay for all the add-ons, than it might be more luxurious).

How to Get to Therme Wien by Public Transport

One of the best things about Therme Wien is how easy it is to reach. You don’t need a car, and it’s very straightforward even if it’s your first time in Vienna.

Simply take the U1 metro line to Oberlaa, which is the last stop. Depending on where you get on, the journey takes about 15 to 30 minutes.

Once you arrive, it’s almost impossible to get lost:

You get off the train and walk through a short pedestrian tunnel
Exit the station
And you’re right in front of the entrance

It’s honestly one of the most stress-free spa journeys I’ve ever had.

Tickets, Entry & How It Works

You can either book your ticket online in advance or buy it on arrival.

I didn’t book ahead because I visited on a quiet Monday, and there was no queue at all. If you go on a weekend or during winter, I’d expect it to be much busier, so booking online might be worth it.

When you arrive, there are different queues for pre-booked tickets and if you still need to buy a ticket. There’s also a self-service check-in. I just went straight to the desk to buy a ticket.

The Wristband System

At the ticket desk, you’ll be given a wristband, which is how everything works inside. Instead of paying upfront, you:

use your wristband to enter the spa
use it to lock your locker
use it to access add-ons like the sauna area
and even use it to pay for food, drinks, or anything from the shop

You don’t pay anything when you enter. Everything is tracked on your wristband, and you pay at the end when you leave.

This is super convenient, but it’s also why the total can add up quickly without you really noticing.

Lockers (Important & Unexpectedly Expensive)

When you enter the changing area, you’ll see a huge space with rows and rows of lockers. You can just pick any free one. Here’s how it works:

Put your belongings inside
Close the locker
Hold your wristband to the lock to secure it

Only your wristband can open that locker again.

If you forget your locker number, there are small stations where you can scan your wristband, and it will show you your locker number.

The cost (and my tip)

What I didn’t expect is that lockers are not included in the entry price.

For a full day, we paid €39 for one locker, which I personally found quite expensive. Because of that, I highly recommend sharing one locker if you’re visiting with someone. That’s what we did, and it worked perfectly fine.

What the Pools Are Like

The pool area at Therme Wien is much bigger than I expected. There’s a really good mix of different pools, so you can easily spend a full day here without getting bored.

Indoor Pools

Two large pools that connect to the outside, so you can swim between indoor and outdoor areas
Three smaller pools, two of which are adults-only and warmer
A lap pool for proper swimming, but the water there is much colder (I didn’t try it)

I especially liked the smaller, warmer pools. I’m quite picky when it comes to water temperature, and some of them were actually properly warm.

Outdoor Pools

Outside, there are a few more pools, including:

Two relaxation pools
Another lap pool
And even a pool bar / drink service, where you can order drinks directly to the pool. Like everything else, you just scan your wristband and pay at the end.

Overall Atmosphere

What stood out to me most:

The whole area feels very spacious
There’s a good variety of temperatures
And on a weekday, it was really quiet and relaxing

There’s also a separate kids area with slides, which is great if you’re visiting with family. But since it’s in a different section, you don’t really notice it if you’re just there to relax.

Sauna Area (What You Need to Know)

If you’ve never been to a sauna in Austria before, there are a few things you should know, because it might be different from what you’re used to.

In Austria, saunas are textile-free, which means you have to be completely naked (swimwear is not allowed)
You’re also not allowed to take any photos in the sauna area (because everyone is naked)
You need to make sure that your whole body is on a towel. This means if you wrap a towel around yourself because you don’t want to be naked, you’ll likely need a second towel as no skin is allowed to touch the wood
In the steam room, you don’t use a towel, instead, you use a hose to rinse the seat before and after using it

Mixed vs Women-Only Area

There’s a large mixed sauna area, which is what I used since I was there with my boyfriend. There are also:

a women-only sauna area
and a men-only area

I had a quick look at the women-only section, and it actually felt more modern and brighter than the mixed area. I’ll definitely try it out when I visit with a friend next time.

Aufguss (Sauna Ritual)

One of the highlights is the Aufguss, which takes place every hour in the outdoor sauna. Here’s how it works:

You arrive a few minutes early and sit down
A staff member comes in and explains the session in German (they just tell you their name, what scent they’ll use and that you can leave if it gets too hot for you, but you can’t come back in again)
They pour scented water over hot stones
Then they wave a towel or a fan to spread the heat

It gets very hot, very quickly.

If you want to try it:

sit on the lowest bench if it’s your first time
and don’t worry, you can leave anytime if it’s too much

Just note: if you leave, you’re not allowed to come back in during that session.

Vegan Food Options at Therme Wien

There is a restaurant inside Therme Wien, as well as a smaller café in the sauna area. But overall, the food was probably the most underwhelming part of the experience for me.

At the main restaurant, there were a few vegan options:

a vegan burger
a tofu wok (rice with vegetables and tofu)
a vegetable wok (rice with vegetables)
a salad buffet (not labelled vegan, but you can tell what is)

They also had:

soy yoghurt with fruit
and a fruit salad

In the sauna area café, the options were more limited:

soy yoghurt with fruit
fruit salad
smoothies

My Honest Experience

We tried the burger and the tofu wok. They were okay, but nothing special. Especially for the price (around €19 each), I expected a bit more.

Honestly, I would recommend bringing your own snacks.

In the main pool area, this isn’t a problem, you can just eat them there.

The only place where it’s not allowed is the sauna area, where you’re expected to eat at the café instead.

Costs: What I Actually Paid

For a full day, we paid:

€38 per person for entry (price depends on the day of the week/season)
€14 extra per person for the sauna
€39 for one locker (which we shared)
and about €19 per dish for food

In total, we ended up paying about €142 for two people.

The main reason it adds up so quickly is the wristband system. You scan your wristband for everything throughout the day. It’s very convenient, but you only see the full amount at the end, which can be a bit of a shock.

For me, the locker was the most unexpected cost. €39 just for a locker feels quite expensive, so I’d definitely recommend sharing one if you can.

Overall, I still think it can be worth it for a relaxing day, but it’s definitely not a budget activity. If you want to keep costs down, bring your own snacks and be mindful of extras.

Best Time to Visit Therme Wien

If you can, I’d definitely recommend visiting during the week. That’s when it’s much quieter and a lot more relaxing.

I went on a Monday in March, and it was really calm. No queues, plenty of space in the pools, and overall just a much nicer experience. I can imagine that weekends, especially in winter, get quite busy.

That said, Therme Wien isn’t just a winter activity.

In summer, they have a large outdoor grass area with lots of sun loungers, which makes it a great spot to relax outside as well.

But personally, I much prefer going in the colder months.

There’s just something about being outside when it’s freezing cold, getting into the warm water. It’s even better if you’re going to the sauna as well, which I always enjoy more when it’s cold outside.

Tips for Visiting Therme Wien

Go during the week if you can: It’s much quieter and a lot more relaxing than weekends
Share a locker: They’re surprisingly expensive, and one is usually enough for two people
Don’t forget your flip flops: You can buy them there, but they’re overpriced
You can rent towels and bathrobes: If you didn’t bring your own, you can rent them there for an extra fee
Bring your own snacks: The food is okay, but not really worth the price
Try the sauna, but be prepared: It’s textile-free, and the Aufguss can get very intense
Sit on the lower bench for your first Aufguss: It’s much more manageable, especially if you’re new to it
Keep an eye on your spending: Since everything is on the wristband, it adds up without you noticing

Thermal Spas in Austria

If you’re visiting Austria, going to a thermal spa is something I’d highly recommend. It’s a big part of the culture here and one of my favourite ways to relax, especially in the colder months.

Therme Wien might not be the most unique spa in Austria, but it’s by far the most convenient option if you’re staying in Vienna. You don’t need to rent a car or spend hours on the train, and you still get a proper spa experience.

If you have more time and want something a bit more special, there are other thermal spas across Austria (like Bad Blumau) that feel more unique and scenic.

I’ll be sharing a full guide to the best thermal spas in Austria soon, so you can compare different options and decide which one suits your trip best.
