Baiyoke Sky Observation Deck

Why go

The payoff is the contrast between two viewing levels. The enclosed deck provides a stable overview, while the revolving platform turns Bangkok into a continuous panorama without requiring a circuit on foot. The tower’s concrete engineering and immense vertical core also make it a useful stop for travelers interested in how high-rise Bangkok was built.

What to look for

• The enclosed observation deck sits on Baiyoke Tower’s 77th floor.
• A revolving open-air viewpoint occupies the 84th floor.
• The tower shifts from a square concrete form to a cylindrical upper section.

The full story

Baiyoke Tower II was conceived in the late 1980s and completed in the 1990s as a concrete skyscraper and hotel in Ratchathewi. Its public experience is concentrated high above the guest rooms: an enclosed observation deck occupies the 77th floor, and a revolving open-air platform sits on the 84th. The building’s structure is as notable as its height. Hundreds of concrete piles were driven through Bangkok clay into a deeper sand layer, supporting a thick foundation mat. Above, a concrete core and hollow columns carry the square tower, while the upper floors shift toward a cylindrical form. Construction relied on self-climbing formwork and concrete pumped to exceptional heights. Those details help the skyline view make sense: the tower is not only a platform above Bangkok but also a record of the engineering required to rise from the city’s difficult ground.

Useful to know

• Choose a day with clear visibility; haze or heavy rain can erase much of the viewpoint’s value.
• Use the enclosed deck for orientation before moving to the revolving level above.
• Check the official ticket page before visiting because observation access and bundled offers can change.
