Bangkok's oldest amusement park facing 6-month closure from flood damage

Bangkok's 118-acre Siam Amazing Park has announced a temporary six-month closure after nearly the entire complex suffered severe flood damage and has remained submerged for five days.

The amusement and water park complex, also known as Suansiam, was hit by flooding triggered by torrential rain in Bangkok since Sept 26, with numerous rides and park attractions submerged in extended inundation.

The site covers about 300 rai of land, about 118.61 acres, in Khan Na Yao district, which has been marked as a highly affected district of the flood-hit capital.

The park officially announced the temporary closure on Wednesday morning.

Wuthichai Luangamornlert, managing director at Siam Park City Co Ltd, told the media that the 2026 flooding was the most severe for the park, differing from the 2011 flood. 

In 2011, only 30% of the site was impacted, Mr Wuthichai said. This time, almost 100% of the park was affected.

Ride machinery has been suspected of water damage.

The estimated loss could be over 100 million baht as the park would lose income during the school break between September and October, as well as from planned year-end activity, he said.

In light of circumstances nonetheless, the management agreed to suspend operations for six months to thoroughly inspect all rides and carry out comprehensive improvements across the entire park.

Once floodwaters recede, a full assessment of the damage will be conducted to support negotiations with financial institutions for rehabilitation financing. 

The restoration is expected to take at least three to four months, according to the management, which expressed hope to reopen the park and welcome visitors again before next year's Songkran Festival.

The park also operates a zoo, where 10 drowning hog deer were rescued from the flood on Sept 27, but six others were found dead in the water.

Siam Amazing Park was founded in November 1980 and remains the oldest amusement and water park complex in Southeast Asia. It is also known locally as the "Bangkok Sea" for its large artificial sea, which has suffered extensive flood damage and will require major renovation work.
