Deep Sleep: The deepest hotel in the world is in Wales
This page may contain affiliate links.

In Wales gibt es seit 2023 ein ganz besonderes Hotel. Das Deep Sleep, so der Name der Lokalität, macht seinem Namen alle Ehre, denn es ist nicht weniger als das am tiefsten gelegene Hotel auf der ganzen Welt. Der Weg zu der Unterkunft ist nichts für schwache Nerven, befindet es sich doch in einer alten Schiefermine. Mehr als 400 Meter unter der Erde erwartet Gäste dann eher spartanischer Luxus. Trotz der gesalzenen Preise für die Übernachtung ist die Nachfrage offenbar groß.

What would be a particularly important criterion for you, dear readers, when booking a guest room? Quite a few of you would probably answer: “The view, of course”. Others might find it important to have enough space and spaciousness. But if you book yourself into Deep Sleep in Wales, you have to forego both and many more amenities that a hostel normally comes with. An overnight stay here will certainly be an unforgettable adventure, as the accommodation is no less than the lowest-lying hotel in the world. In any case, a look at its website reveals that demand is high despite the high prices.

Das Deep Sleep wäre wohl nichts für Menschen mit Klaustrophobie, denn laut dem Web-Auftritt des Betreibers befindet es sich 419 Meter tief unter der Erde. Die Unternehmer-Firma mit dem treffenden Namen „Go Below“ (zu Deutsch etwa „Geh nach unten“) eröffnete es im April 2023 in der weltgrößten und -tiefsten Schiefermine, wo der Stein zuvor für 200 Jahre abgebaut wurde. Ein labyrinthartiges Netzwerk aus engen Gängen und Stollen, die immer tiefer unter die Erde führen. Und wer im am tiefsten gelegenen Hotel auf dem Planeten übernachten will, muss sich seinen Weg zum Schlafplatz, geführt von einem Guide, selbst und zu Fuß in den Abgrund bahnen.

Dafür werden Gäste vom Betreiber unter anderem mit Helm, Stirnlampe und speziellen Stiefeln ausgestattet. Sodann starten sie eine etwa 45-minütige Wanderung durch die malerische Landschaft des Snowdonia Nationalpark bis zum Eingang der Mine. Laut „CBS“ dauert der Abstieg zum Deep Sleep insgesamt etwa vier Stunden und ist durchaus nervenaufreibend. So muss man etwa eine Zipline benutzen und sich mitunter durch enge Schächte regelrecht hindurchzwängen. Ein Mitarbeiter von Deep Sleep sagt auf Sunnytrips-Anfrage: „Die gesamte Strecke wird regelmäßig von einem Mineninspektor auf ihre Sicherheit geprüft, genauso wie die Schlafstätten.“ Einmal unten angekommen, erwartet die Abenteurer dann eher ein archaischer Komfort. Auf eines müssen sie dabei aber nicht verzichten.

Because even if there is no running water in Deep Sleep, WiFi is actually available thanks to a one-kilometer-long special cable underground. Of course there is no cell phone reception down here. The accommodation has four spartan huts and the so-called “grotto”, a kind of private room. Whether romantic feelings arise down here with a constant temperature of only 10 degrees Celsius remains questionable. If you want, you can bring your own food for this special trip. The operator also offers a simple breakfast and dinner. The menu options can be viewed on the official website.

The guide and a technical staff member of the company stay with the guests in deep sleep throughout the night. Sleep, if any, will be short. Because you have to get up again at 8 a.m. in order to start the strenuous climb back up by 10:30 a.m. at the latest. The tours sometimes start several times a week until late in December.

“So far, more than 1,000 people have stayed with us,” say the operators. And that despite the fact that you have to dig deep into your pockets for a night of deep sleep. The “room” in one of the cabins costs an impressive 399 pounds, which is the equivalent of almost 475 euros. The “Grotte” is even more expensive at 599 pounds per night (a good 710 euros). Please note, among other things, that children aged 14 and over are only allowed to stay overnight in the deepest hotel in the world. All questions about your stay can be answered on the official website.

The deepest hotel in the world is also always a challenge for the Deep Sleep employees: “Re-making the beds at a depth of 419 meters is not exactly an easy job.” The company founder came up with the idea a few years ago because he had always been a big fan of adventures underground. During tours through the mine, more and more guests asked whether it was possible to sleep down there. It is not clear how much the company invested in the unusual hotel. But: “Seeing the guests’ reaction to this special place makes all the effort worth it.”
