Best hotels with underwater rooms: Top 7 places to stay under the ocean's surface with sea creatures outside your window

"Underwater" hotels today are no longer the fiction of some fantasist but a very real opportunity to observe marine life in different parts of the world from an unusual angle. In recent years, tourist services have been supplemented with such an "underwater" offer, which quickly gained fans among travellers from all over the world. It's a very different experience, allowing you to get to know the ocean floor and the inhabitants of its waters more than snorkeling and scuba diving can provide.

You may have already heard of the first underwater rooms appearing in Dubai hotels, but such original accommodations have popped up all over the world. Such experiences naturally can't be cheap, but there are hotels with underwater rooms at a pretty reasonable price as far as first-class resorts go. You can vacation on the ocean and dive into its abyss countless times and admire the constellations of reef fish, but sleeping in the ocean's water column will give you a completely incomparable experience.

Get ready for an exciting adventure at these top hotels with underwater accommodations.

One of Sweden's most unusual "underwater" hotels, Utter Inn, provides its own little nook below the surface. It is located in the town of Västerås about a kilometre from the mainland.
