Sunset in Bangkok hits differently when you are watching it slip behind the mighty Chao Phraya River. The river bends, the long-tail boats keep moving, and the city lights flick on one by one across the skyline. That is the stunning moment a great rooftop bar riverside in Bangkok delivers, and it is exactly what guests find at Cloud 36 at Chatrium Hotel Riverside Bangkok.
As home to one of the city's most distinctive riverside hotel rooftop bar experiences in Bangkok, our hotel also pairs this sky-high venue with a full collection of dining concepts. Below, we walk through Cloud 36 as the centrepiece, then take you through the wider food and drink line-up at Chatrium Hotel Riverside Bangkok.

Cloud 36, a beloved rooftop bar in riverside Bangkok, sits perched above the Chao Phraya on the 36th floor of our hotel. The bar offers a true 360-degree panorama, where you can watch the river traffic on one side and the city skyline glow on the other. As a rooftop bar at a riverside hotel in Bangkok with Chao Phraya views, this is the kind of vantage point you simply cannot get from a venue tucked into the city centre. Water, light and skyline meet in one wide-open frame.
The drinks concept is Spirits of the Orient. Cocktails are built around premium spirits, Asian herbs, spices and seasonal fruits, joined by a wine, champagne and zero-proof selection. Each drink takes its cue from an iconic Asian neighbourhood. For instance, the Charoen Krung Road blends gin infused with lemongrass and starfruit, lifted by triple sec, lemon and grapefruit bitters. The Yaowarat Mule channels Chinatown with bourbon infused with goji berry and honey galangal, finished with lime and ginger beer. The Kombu Margarita brings Japanese flair through mezcal infused with kombu seaweed, apricot liqueur, yuzu and a hint of wasabi spray. Each glass tells a story, best enjoyed with the skyline as your backdrop.
By day, Cloud 36 turns into a sky-high lounge for Afternoon Tea, featuring Cantonese dim sum, scones and pastries from the Michelin-starred chefs at Silver Waves by Boon, served with TWG teas. From late afternoon into the evening, the room shifts mood again. On selected evenings, live music and guest shifts add extra energy to the night.
It works for plenty of occasions. Sundowners with friends, after-dinner drinks once you have eaten downstairs, a date night with something a little more memorable, or a corporate social where the view does the heavy lifting. As a rooftop bar by riverside Bangkok with a Chao Phraya river view, Cloud 36 is open daily from 16:00 to 01:00.*

Cloud 36 is the headline act, and our hotel in Bangkok has built a full collection of dining concepts to round out the evening.
Silver Waves by Boon sits on the same 36th floor as Cloud 36 and brings Cantonese fine dining to the river. Led by Michelin-starred Chef Ho Chee Boon, the menu reflects heritage and modern artistry, served alongside skyline views. Open daily for lunch from 11:30 to 15:00 and dinner from 18:00 to 22:00.
River Barge is the casual riverside option, set right on the banks of the Chao Phraya. The menu spans Thai and international dishes, from local street food to contemporary plates, with regular themed buffet evenings adding variety throughout the year. Open daily from 06:30 to 22:00.
Lobby Lounge is the all-day social spot, with floor-to-ceiling windows looking out to the garden. It serves freshly made cakes, pastries, cookies and drinks, and hosts a rotating Afternoon Tea programme that changes through the seasons. Open daily from 06:00 to 22:00.
Flow is the poolside bar. Drinks, snacks and meals get delivered straight to your sun lounger, so you can spend a Bangkok afternoon by the water without lifting much more than a glass. Open daily from 10:00 to 23:00.
Across all venues, our hotel near the Chao Phraya river runs an evolving line-up of seasonal offers, themed dinners and limited-edition cocktail experiences. It is worth checking what is on before your visit. That gives you a clear path for the evening: start at Flow by the pool, move through the Lobby Lounge, head to River Barge or Silver Waves by Boon for dinner, and end the night at Cloud 36.
Cloud 36 is a rooftop bar that holds its own as a reason to make the trip across town. Pair it with the rest of the dining collection at our hotel in Bangkok, and you can build an entire evening around the property without leaving the riverside.
