Europe boasts some of the world’s best hotels. You can find grand palaces on Venetian canals, clifftop retreats over the Aegean, and converted castles in the Scottish Highlands. For travelers seeking a truly unique experience, Europe’s underwater hotels stand out. They provide a stay unlike any hotel. Here, you can fall asleep surrounded by water and watch the aquatic world glide by your windows. No marble lobby or Michelin-starred restaurant can match this.
The honest picture of underwater hotels in Europe is this: the continent currently has two operational properties where guests can sleep underwater, in very different countries and very different contexts. Sweden offers the world’s most atmospheric lake underwater experience at Utter Inn. Belgium provides a unique wildlife experience at Pairi Daiza Resort’s Walrus House. Both are worth understanding properly before you book.
This guide explains what’s available in underwater hotels in Europe. It details each experience and shares what’s coming next.
Underwater Hotels in Europe: The Current Options
Utter Inn — Lake Mälaren, Västerås, Sweden
The most genuinely, completely underwater hotel room in Europe.
What seems like a cheerful red cabin on a lake near Västerås is actually the gateway to Europe’s most remarkable overnight experience. Utter Inn started as an art project and became a cult travel spot. It was created by Swedish artist Mikael Genberg. He focuses on placing living spaces in unique locations that others overlook.
The structure is divided into two parts. The small cabin floats on a Swedish lake. It’s painted classic Scandinavian red with white window frames, giving it a comically domestic feel. Inside, you’ll find a basic kitchen with a small cooker and a toilet. Descend through a hatch in the floor, and you’ll find the true draw here: a bedroom three meters below Lake Mälaren’s surface. It has windows on all four sides, offering views into the lake’s freshwater world.
The room itself is modest — two single beds, a table — and that modesty is entirely the point. Utter Inn is not asking you to admire its amenities. Sit quietly in the middle of a Swedish lake, three meters underwater. Watch the fish swim silently in the unique stillness found beneath fresh water. Perch, pike, and roach drift past the windows. In winter, when Lake Mälaren freezes, everything feels different. Ice builds up on your skylight windows, and the outside world turns a beautiful blue-white, sparkling like crystal.
Guests are taken out by an inflatable boat from Västerås harbor and left to their own devices. Dinner can be delivered by boat in the evening if arranged in advance. Breakfast and water are provided. There is no Wi-Fi, which is — without question — part of the appeal.
The peace and quiet is what guests consistently describe as the revelation. This is a place to be alone or to spend quality time with someone close to you, at the pace of water rather than the pace of daily life. Västerås is approximately one hour from Stockholm by rail, making Utter Inn entirely realistic as a one-night addition to a Stockholm city trip.
Location: Lake Mälaren, Västerås, Sweden (approx. 1 hour from Stockholm) Best for: Couples; those seeking contemplative solitude; Scandinavian travel enthusiasts; anyone who finds the idea of a Swedish lake more appealing than a tropical ocean. Don’t miss: Arriving at dusk and watching the lake light change from inside your underwater bedroom. In winter, the iced-over lake produces views that photographs cannot adequately capture. Practical note: The experience is deliberately rustic. Pack your own food and drink beyond what’s provided, and embrace the absence of phone signal as a feature rather than a flaw.
Pairi Daiza Resort — Walrus House, Brugelette, Belgium
Europe’s most unusual underwater hotel — and one of its most family-friendly.
Pairi Daiza is the biggest and most famous zoo in Belgium. It has been voted “Best Animal Park in Europe” many times. Here, you can find more than 7,000 animals from around the world. Since 2019, you can sleep inside the park. Not just beside it or near it, but right within the animal habitats. You’re separated from the wildlife by specially designed glass.
The Walrus House is the property’s underwater offering and its most singular experience. The Walrus House is in the Land of the Cold section of the resort. This area focuses on Arctic and subarctic environments. The rooms overlook the walrus habitat’s aquatic area. Only underwater viewing is allowed. Pairi Daiza emphasizes that these rooms have no above-ground views. You view the scene from beneath the waterline. A large glass wall lets you see the habitat. Walruses—massive, long-tusked, and truly curious—glide through the water around you.
The design leans entirely into the Arctic aesthetic: ice-blue, white and silver coloring, faux fur rugs, whitewashed walls with ice effects, white onyx bedside tables, and gilded brass fittings. The effect is part snow cave, part luxury suite — an unlikely combination that works rather well. You go to sleep in an Arctic ice environment and wake up to a walrus inspecting you through the glass.
This is not a typical marine hotel. Instead, it’s a managed zoo environment, not the open ocean or a natural lake. Pairi Daiza offers something special: a family-friendly, year-round experience with amazing animals. You get two full days in the park, plus breakfast and dinner, all in a well-designed setting.
Rates start at approximately €1,151 for two adults for the Walrus House package, including two-day park access, meals, and a welcome gift. The resort offers animal-facing rooms for guests who want both walrus views and polar bear sightings. You can also see penguins, meet Siberian tigers, and enjoy Steller sea lions. This variety lets families with different interests find something special.
Location: Brugelette, Belgium (approx. 1 hour from Brussels by car) Best for: Families; animal lovers; couples wanting a genuinely unusual European short break. Don’t miss: The exclusive early morning access before day visitors arrive — the animals are most active and the park is at its most peaceful. Practical note: Book as far ahead as possible. The animal-facing rooms at Pairi Daiza are some of the most popular hotel experiences in Belgium. They often sell out early, especially on weekends and during school holidays.
How Europe’s Underwater Hotels Compare
Europe has two underwater hotels, and they offer different experiences. Choosing between them depends on what you want.
Utter Inn is wild, rustic, genuinely immersive, and deliberately stripped-back. You are alone (or nearly so), in the middle of a real Swedish lake, watching freshwater fish in their natural habitat. There is no butler service, no curated dinner experience, no theme park surrounding you. It is, in the best possible sense, just you and the water. It appeals to travelers who value contemplation, quirkiness, and the particular beauty of Nordic nature.
Pairi Daiza’s Walrus House is curated, comfortable, family-friendly, and spectacular in a very different way. You are in a hotel environment with full zoo access, excellent food, and the extraordinary bonus of a glass wall into a walrus habitat. It attracts families, couples seeking real comfort with a twist, and animal lovers who crave wildlife encounters.
Neither is better. They are simply different answers to the same question: what does it feel like to spend a night with a body of water between you and the world?
Bonus: Europe’s Underwater Restaurant Worth Knowing
Travelers in Europe seeking underwater fun—without an overnight stay—can enjoy Under. This is Europe’s first underwater restaurant, located near Lindesnes at Norway’s southern tip. This amazing concrete structure goes five meters below the North Sea’s surface. It has large windows that offer views of the seabed. It opened in 2019 to great praise. Though not a place to stay overnight, it offers a unique underwater dining experience. It’s truly worth planning a trip to Norway for. It seats 35 guests and books up considerably in advance.
What’s Coming Next?
Europe has plenty of ambition when it comes to underwater hospitality concepts. The Mediterranean, especially Greece, Croatia, Italy, and Spain, is seen as the top area for major European growth in the next ten years. The Mediterranean coastline has amazing marine life, great luxury hotels, and warm, clear waters. This makes it a perfect spot for underwater suites, like those found in the Maldives and Dubai.
Nothing is operational yet. But Europe’s underwater hotel scene is almost certainly at the beginning of its story rather than the end of it.
Planning Your European Underwater Hotel Trip
Getting to Utter Inn: Västerås is approximately one hour from Stockholm by direct train from Stockholm Central Station. Fly into Stockholm Arlanda (ARN), take the Arlanda Express to Central Station, and connect to Västerås. The hotel is reached by inflatable boat from Västerås harbor — a short trip in itself.
Getting to Pairi Daiza: Located in Brugelette, approximately one hour by car from Brussels. Public transport access is available via train and bus. The park is 65 hectares — allow at least two full days to do it justice, which aligns perfectly with the two-day park access included in all overnight packages.
Best time to visit Utter Inn: Open year-round. Summer (June–August) offers long Scandinavian evenings and warm temperatures. Winter visits can be magical. The lake might be frozen, creating a unique experience. Ice forms above the underwater bedroom windows, offering a sight like no other.
Best time to visit Pairi Daiza: The park operates approximately eleven months of the year, closing briefly in January. Spring and early summer are ideal. Weekday visits are always quieter than weekends.
