it’s evolved into its final form: an opulent, colonial-style grand hotel that’s quickly become a favorite among upper-crust locals.
“Occupying a series of low-slung buildings, overlooking the Royal Bangkok Sports Club, Anantara Siam might not look like much from the outside, but inside... has firmly established the hotel’s spot at the top of the Anantara food chain.”
Right in the middle
Well-located: walkable to some things, a short ride to more.
Set along Rajadamri Road facing the Royal Bangkok Sports Club golf course, the hotel sits steps from Ratchadamri station and Lumphini Park.
The rooms
Polished teak furnishings and silk wall panels accent the rooms, while ground-floor Garden Pool Suites open directly to private plunge pools.
The pool
Bring a swimsuit.
The 25-meter outdoor pool is framed by tropical gardens, retro fringed umbrellas, and traditional wooden gazebos.
The spa and gym
Private spa suites offer sunken soaking tubs and steam rooms. Downstairs, the 24-hour health club adds squash courts.
At the table
Courtyard tables serve regional Thai curries and handmade pastas, while Aqua Bar pours cocktails beside the koi ponds.
Although it opened in 2015 (it took over the building from the Four Seasons), the hotel already feels settled into its plush surroundings, exuding a classic, timeless feel.
How it began
Architect George Wimberley designed the low-slung compound in 1983, originally opening as Bangkok's first Peninsula before becoming Anantara's flagship.
