Pool + Gym

Tropical gardens set the scene for leisurely afternoons in the city.

Surrounded by lush tropical gardens, the newly refreshed swimming pool channels the atmosphere of a secluded urban resort. Designed for both relaxation and unhurried afternoons, the space combines contemporary comforts with the hotel’s signature sense of calm. Shaded lounging areas and private cabanas offer plenty of space to settle in between swims, while swaying palms reinforce the feeling of being removed from the city beyond. At The Garden Terrace, guests can linger over poolside dining without having to leave the greenery behind.

The newly transformed Fitness Center takes a holistic approach to movement and recovery, pairing expansive workout spaces with dedicated areas for slowing down afterward. State-of-the-art Technogym equipment supports both cardio and strength training, while a dedicated Pilates studio provides additional options for maintaining a routine while traveling. Beyond the workout floor, redesigned locker rooms feature steam rooms, whirlpool facilities, experiential showers, and a restorative salt room. Dedicated relaxation areas round out the experience, making recovery as much a part of the wellness offering as the workout itself.

Tranquil treatment suites provide a quiet setting for signature rituals and personalized treatments designed around relaxation, restoration, and balance.

Whether incorporated into a broader wellness routine or reserved for a restorative afternoon, the spa carries the hotel’s sense of calm into every treatment.
Restaurant + Bar

Spice Market celebrates Thailand’s culinary heritage through bold flavors and time-honored recipes.

A longstanding dining institution at Anantara Siam since the hotel’s earliest days, Spice Market – A Thai Dining Room celebrates the breadth of Thai cuisine through time-honored recipes and thoughtful preparation. Inspired by Thailand’s traditional spice markets and rich culinary heritage, the restaurant brings together aromatic herbs, bold spices, and familiar Thai flavors in a setting rooted in local culture. The experience feels connected to tradition while maintaining a contemporary point of view, making Spice Market an inviting introduction to Thai cuisine as well as a destination for returning guests.

Aqua has been a social destination in the heart of Ratchaprasong for more than two decades, earning recognition among Thailand’s notable bars. Tucked into a garden setting, the bar offers an atmospheric place to settle in for cocktails away from the pace of the surrounding city. Its Secret Garden menu invites guests into the whimsical world of Quill, Aqua’s signature duck and storyteller. Cocktails are imagined as playful “potions,” drawing inspiration from hidden gardens, twilight rituals, and a spirit of discovery. The concept brings a sense of storytelling to the experience while preserving the intimate garden atmosphere that has long defined Aqua.
  • Vibe
    Anantara Siam feels rooted in an earlier era of Bangkok hospitality, balancing old-world Siamese grandeur with the relaxed rhythm of a resort. High ceilings, hand-painted silk murals, traditional Thai details, and lush gardens give the property a strong sense of character that distinguishes it from the city’s more contemporary hotels. Despite its central setting, the hotel never feels entirely urban. Tropical greenery, the garden-framed swimming pool, and quieter corners throughout the property create space to slow down between outings. The result is polished without feeling overly formal, with a strong connection to Thai design and culture woven throughout the experience.
  • Who's it for?
    Anantara Siam is particularly well suited to travelers who prioritize character, convenience, and a strong sense of place. Its central location and easy BTS Skytrain access work well for first-time visitors and returning Bangkok travelers alike, while the resort-style layout offers a welcome change of pace after time spent exploring the city. Couples will appreciate the atmospheric restaurants, garden setting, and wellness offerings, while families benefit from the spacious accommodations, pool, and room to spread out. Design-minded and culture-focused travelers will find plenty to engage with in the hotel’s architecture, Thai-inspired interiors, Jim Thompson collaboration, and longstanding connection to Bangkok.
  • Location
    Anantara Siam Bangkok Hotel sits along tree-lined Ratchadamri Road in the Ratchaprasong district, placing guests in one of Bangkok’s most established central neighborhoods. The location offers convenient access to the city’s major shopping, dining, cultural, and business destinations while retaining a sense of calm within the hotel itself. Easy access to the BTS Skytrain makes exploring farther afield straightforward, whether guests are setting out for Bangkok’s historic sites, discovering another neighborhood, or heading across the city for dinner. Back at the hotel, tropical gardens create a noticeable transition from the energy outside.
