Ozone is the altitude record of this list made real. It occupies Level 118 of the International Commerce Centre in West Kowloon, roughly 480 metres above Victoria Harbour, and is billed by The Ritz-Carlton as the highest rooftop bar in the world. That claim is endlessly repeated because standing on its open-air terrace genuinely feels like it: the Hong Kong Island skyline you normally crane up at is suddenly laid out far below you, and the harbour traffic looks like toys. It is more spectacle than intimacy, which is why we place it eleventh, but no honest world ranking can leave out the planet's highest place to hold a cocktail.
The building: Hong Kong's tallest tower
Half of Ozone's drama is the address. The International Commerce Centre is a 484-metre supertall skyscraper, the tallest building in Hong Kong and, on completion in 2010, one of the tallest in the world. The Ritz-Carlton occupies its uppermost floors, from the 102nd up to the 118th, which puts Ozone at the very top of the tower. A quirk of the numbering adds to the mythology: the building has only 108 actual storeys, but floors containing the number four, considered unlucky in Cantonese, were skipped, inflating the count so that the top floor is labelled 118. The same tower holds the sky100 observation deck far below on Level 100, and a Ritz-Carlton swimming pool that has been recognised as the highest in a building in the world. Ozone is the crown of all of it.
The ascent: part of the experience
Getting to Ozone is a set-piece in itself. Guests enter at the ICC's ground-level lobby and ride a button-less express elevator that climbs more than ninety storeys to the Ritz-Carlton's sky lobby in about a minute, ears popping on the way. From there a second, Ozone-branded lift completes the journey to Level 118. By the time you step out into the bar you have already travelled further vertically than most buildings on earth can offer, and the sense of arrival, of having climbed clear of the city, is a deliberate part of the theatre. It primes you for the moment the view opens up.
The view: the harbour from the top of the world
The reason to come is the outlook, and it is genuinely staggering. Ozone pairs an indoor bar with an open-air terrace looking south over Victoria Harbour to Hong Kong Island, with the Kowloon peninsula spread out below. From nearly 480 metres up, the famous skyline is beneath you rather than in front of you, the skyscrapers of Central reduced to a glittering carpet and the harbour a dark ribbon crossed by ferries. The nightly Symphony of Lights show plays across the towers below, and on a clear evening the sense of scale is almost dizzying. Come toward dusk, when the sky still holds colour and the city begins to switch on its lights one tower at a time, and the terrace delivers one of the great urban views on the planet.
The design: an Edenic experiment
Inside, Ozone is as surreal as the view is real. The interior was created by the Tokyo studio Wonderwall, led by the designer Masamichi Katayama, around a concept its makers called the "Edenic Experiment," a man-made environment of nature reimagined in an imaginary world. The result is deliberately bold and a little bizarre: angular forms and lavish materials, a honeycomb pattern inlaid into black marble flooring and echoed in a dramatic suspended ceiling, a sleek white marble bar, artworks set along the seating, and a blue-hued ambience that shifts as the evening goes on and the lighting turns the room into a nightspot with a resident DJ. It is a designed jolt against the literal view outside, and it is why Ozone reads as an experience rather than simply a high bar.
The drinks and the food
The programme is cocktail-led, and it has kept pace with the setting. The current menu is themed around the "Five Elements," a set of drinks representing fire, metal, water, earth and wood; the "Water" serve, for instance, mimics ocean salinity with clarified grapefruit, umami bitters and rum. Cocktails run to around twenty-five US dollars, and there is a deep list of champagnes, fine wines and spirits behind them, overseen by bar manager Arvy Bryan Benitez. The food is modern Asian-style tapas, small plates alongside oysters, caviar, sliders and daily sushi, designed for grazing rather than a full meal. It is drinking and picking at the top of the world, not a sit-down dinner, and it suits the room. Over the years the bar's signature cocktails have changed with each menu, so rather than chase a particular famous drink, order from the current list and let the team steer you.
Planning your visit
Ozone is open Monday to Friday from 4:00pm to 1:00am, Saturday from 2:00pm to 1:00am, and Sunday from noon to midnight, with a Sunday brunch as well. There is a minimum spend, currently 200 Hong Kong dollars per guest indoors and 500 for the coveted outdoor window seats, plus a service charge, and the prized terrace window chairs are limited and go quickly, so arriving near opening or booking ahead is wise. The dress code is smart casual, ruling out athletic wear, flip-flops, rubber footwear and, for men, sleeveless shirts and shorts; guests aged fifteen and under are welcome daily before 9:00pm. Reservations are made through the hotel. For the best of it, aim for a terrace window seat in the run-up to sunset.
A note on the "highest bar in the world" claim
Ozone leans hard on its billing as the world's highest bar, and it is worth being precise about it. When it opened in 2011, the claim was straightforwardly true, and it held the title for years. Since then, bars at even greater elevation have opened elsewhere, notably in Dubai's Burj Khalifa, so the honest framing is that Ozone is billed as, and was, the world's highest bar, and remains one of the very highest rooftop bars anywhere and the highest in Hong Kong. None of that diminishes the experience. Whether or not it holds an outright record on any given year, standing on an open-air terrace approaching 480 metres up, with a great world city glittering beneath you, delivers a sense of altitude that almost nothing else can match. The claim is marketing; the vertigo is entirely real.
What to order
Because the cocktail list changes with each menu, the smart approach at Ozone is to drink from the current selection rather than hunt for a particular famous serve. The present menu is built around the Five Elements, a set of drinks themed on fire, metal, water, earth and wood, and it rewards ordering by mood or by curiosity; the elemental serves are designed to be distinct from one another, so a table can explore the whole idea across a few glasses. If cocktails are not your focus, the champagne and wine lists run deep, and a glass of champagne on the terrace at sunset is one of the classic ways to experience the room. Pair whatever you choose with a few of the Asian-style small plates, the oysters or the sushi, and treat the visit as grazing at altitude rather than a full dinner. However you order, remember that much of what you are paying for is the view and the height, so give yourself time to enjoy them.
The window seats, and how to get one
The single most important piece of planning at Ozone concerns where you sit. The open-air terrace has only a limited number of outdoor window chairs, the seats that put you right at the edge with the harbour falling away below, and they carry a higher minimum spend for good reason: they are the best seats in the house and the ones everyone wants. They are not endless, and on a busy evening they fill fast, so the way to secure the full Ozone experience is to arrive close to opening, or to make your intentions clear when you reserve through the hotel. If a terrace window seat is your goal, plan around it rather than leaving it to chance, because the difference between the indoor bar and the outer rail, in a place this high, is the difference between seeing the view and feeling it.
Best time to go
Dusk is the answer. Ozone is at its most spectacular in the transition from daylight to dark, when the sky still holds colour and the towers of Hong Kong Island begin to light up one by one far below. Arriving in the late afternoon or early evening, before the sun goes down, lets you watch the whole change from a single seat, and it gives you the best chance at a terrace window chair before the evening crowd builds. Daytime visits have their own reward, with clearer, glare-free views for photography and a calmer room, while later at night the DJ and the shifting blue lighting turn the space into more of a nightspot. For most people, the hour bracketing sunset is the one to aim for, so time your booking accordingly.
The setting: West Kowloon
Ozone sits atop the ICC in West Kowloon, on the harbour front across the water from the traditional bar districts of Hong Kong Island. The tower is directly connected to the city's transport network and sits above a major mall and the sky100 observation deck, so it is easy to reach and forms part of a wider destination on the Kowloon waterfront. That location is also why the view works so well: looking south from West Kowloon, you get the full sweep of the Hong Kong Island skyline and the harbour between, the classic postcard of the city, seen from far higher than any conventional vantage point. It makes Ozone a natural high point, in every sense, of a visit to Hong Kong, whether as the start of a night out or a destination in its own right.
Spectacle, honestly
It is worth being clear-eyed about what Ozone is and is not, because it shapes whether you will love it. This is not a quiet craft-cocktail den where the drink is the whole point and the room disappears around it. It is a large, dramatic, designed spectacle, with a DJ, a minimum spend, a dress code and a steady flow of visitors who have come, understandably, for the highest view on earth. If you arrive expecting an intimate neighbourhood bar, the scale and the buzz may surprise you. But if you take it on its own terms, as a piece of pure vertical theatre, it is hard to beat. The cocktails are genuinely well made, the design is unlike anywhere else, and the view is simply in a category of its own. Set your expectations to spectacle rather than intimacy, and Ozone delivers exactly what it promises: an unforgettable night at the top of a great city, the kind of experience you plan a trip around rather than stumble into, and the reason it belongs on any serious list of the world's best rooftop bars.
The verdict
Ozone is the world's highest rooftop bar made good on its promise. It offers an open-air terrace roughly 480 metres above Victoria Harbour, with the Hong Kong skyline laid out beneath your feet, a surreal, beautifully designed interior, a serious cocktail programme and the sheer, once-in-a-lifetime thrill of drinking from the top of one of the planet's great cities. It is spectacle rather than intimacy, and a night here comes with a minimum spend and a dress code to match its ambition, but for pure vertigo-and-neon theatre nothing else on this list competes, which is why it earns eleventh place. Dress smart, go up before sunset, claim a terrace window seat if you can, and watch Hong Kong ignite 118 storeys below. There are quieter bars and better cocktails elsewhere in the city, but there is nowhere on earth quite this high to raise a glass, and that alone makes the trip to the top worth taking.
