Complete Guide to Aqua Dome, Austria: Thermal Baths, Sauna World, Spa 3000 & Hotel

Aqua Dome is arguably the most iconic thermal spa (“Therme” in German) in Austria, if not the entire European Alps. 

With its floating basins and cone-shaped covered stairway, the whimsically-designed Therme is both futuristic and fantastical. Day and night, it looks like a beacon, beckoning you to bathe in its thermal waters amidst the mighty peaks of the Austrian Alps

Located in Längenfeld in Ötztal Valley, Aqua Dome welcomes day visitors as well as hotel guests throughout the entire year. 

While Aqua Dome is a new and modern complex, people have been bathing in the Längenfeld hot springs since the 16th century. From 6000 feet underground, a sulfur spring bubbles up to the surface at a rate of 3-4 liters per second.

This mineral-rich water streams into the thermal baths, thus making Aqua Dome a legally-recognized mineral spa. Each Day, 80,000 liters of thermally heated spring water flow into Aqua Dome.

In this post, you’ll learn about what exactly the Aqua Dome Therme complex is, which entry ticket to purchase, and helpful tips for visiting. 

If you want to experience everything Aqua Dome has to offer, we highly recommend staying at least one night in the Aqua Dome Hotel. As a hotel guest, you have exclusive access to the Spa 3000 wellness area and the Panorama Relaxation Room as well as early access to the Thermal Baths and Sauna World. For the best rates, check out

This payment system is standard across Thermen. It’s safe and convenient, because you don’t have to carry around your wallet/cash through the Therme.

Therme Restaurant

The canteen-style Therme restaurant is accessible to all guests. 

Sauna World Bistro

The bistro inside the Sauna World offers a number of meals and drinks in a more secluded setting.

As a hotel guest, you’ll eat a multi-course gourmet dinner in the hotel restaurant. You’ll also eat your breakfast in the hotel restaurant. Tip: don’t overlook the extensive local cheese buffet at the end of dinner. I’ve never seen anything like it. 

Book your stay at Aqua Dome.

Aqua Dome Hotel: 4 Star Superior Spa Hotel

We recommend staying in the Aqua Dome Hotel, in order to get access to the Spa 3000 and early access to the Therme.

Dinner and breakfast is also a treat to look forward to. The hotel is staffed by an amazing team, who are friendly, helpful, and professional. Our experience staying here far exceeded our expectations.

The only thing that could be improved is the bedroom decor and upholstery, which are now dated.

To learn more about our experience, read our Aqua Dome Hotel Review.

When to Visit Austria 

Summer and early Fall are our favorite seasons in Austria.

Getting around Austria

Austria has an excellent public transit system. We’ve used it extensively to travel throughout the country. We highly recommend using transit if you’re visiting cities (Vienna, Salzburg, Innsbruck, Graz, etc…), and/or doing hut-to-hut hikes. 

Some areas like Mayrhofen, Schladming and Lech am Arlberg have wonderful seasonal transit systems in place (e.g. summer hiking buses). However, if you’re not visiting during the high season, bus frequencies are significantly reduced and it’s far easier to get around with your own vehicle. 

If you’re planning on visiting multiple destinations across  Austria, we recommend renting a car. 

Use these road trip itineraries for trip planning inspiration:

Car Rental 

We recommend using the car rental reservation platform to search for and book car rentals. This easy-to-use booking platform compares car rental deals from 500+ trusted providers, so that you can choose the best option for your trip.

If you’re driving into Austria from a neighboring country, don’t forget to purchase a vignette at/near the border.

    • Hi Andrew,
      Are you looking for organized tours? I believe the Aqua Dome Hotel offers daily trips.
      During our visit to Ötztal, we hiked the Hochoetz Miner’s Trail (cableway ascent/descent from Oetz), visited Piburger See, and climbed the Stuibenfall waterfall via ferrata.
      All the best,

  1. Ahoj je možný navštívit koupání v termalu na 3hodiny bez reservace Děkuji (Hello, it is possible to visit the thermal baths for 3 hours without a reservation) Thank you
