What opens on 19 November?
Siam Amazing Park, also known as Suan Siam, in Khan Na Yao district, is preparing to reopen on 19 November 2026, according to the Bangkok Post. The date matches the park's 46th anniversary and the start of its 47th year of operation; the park opened in 1980.
The return is partial. On reopening, only the water park and selected amusement rides are due to operate, the same report says. The rest of the 118-acre site is not listed among what opens on the first day, so a visit in the first weeks is best planned around the water park rather than the thrill rides. For other options in the capital on the same trip, see things to do in Bangkok.
Why has the park been shut?
Flooding in September damaged part of the park, with some ride components severely affected, the Bangkok Post reports. Management first announced a six-month closure, then shortened the restoration period and set the November date.
Before reopening, a team from the Engineering Institute of Thailand inspected the site on Friday, led by Chuchai Sujivorakul, a structural and concrete engineering specialist at King Mongkut's University of Technology Thonburi, according to the newspaper.
What will a visit cost?
The Bangkok Post reports that the park plans annual memberships at 1,000 baht, half the regular price, for unlimited visits during the year. The newspaper adds that final prices and the details of the offer are still being decided, so nothing is fixed yet.
Daily admission prices are not given in the reports, and the fee is likely to depend on which zones are open. Budget for the water park only until the park publishes its full price list.
Does it fit into a Bangkok trip?
The park sits inside Bangkok, so no transfer to another province is needed, but it still takes most of a day once you add travel and changing time. Families with younger children are the main audience for a water-park-first reopening; our Thailand with kids guide covers how to pace a day like this in the heat.
If you would rather keep the day flexible, several day trips from the city can be booked at short notice and do not depend on a single site reopening — compare them in our Bangkok day trips guide.
