This guide explains what opens, what stays closed, and what to check before you plan a visit. It also covers why the park closed and when full operations are expected.

When Is the Siam Amazing Park Reopening?

Quick answer: Siam Amazing Park is set to reopen on November 19, 2026, starting with the water park zone. Theme park rides and attractions stay closed for safety inspections, and full operations are expected by March 2027.

The park is in the Khan Na Yao district of Bangkok, away from the central city area. It opened on November 19, 1980, so the reopening date falls on its 46th anniversary. Many locals still call it Suan Siam, its older name.

Thai PBS World reported the reopening plan on November 4, 2026. Plans can change after safety checks, so confirm the date with the park before you travel.

Water Park Zone and Rides Reopening on November 19

The water park zone is the main area planned to reopen on November 19. Reports do not confirm which rides, if any, will run in the early phase, so treat every ride as closed until the park says otherwise.

Engineers from the countries where the rides were made are due to check each ride before it runs again. Management expects full operations by March 2027, which is a target and not a fixed date for every attraction.

Earlier, management said it wanted the whole park open before the Songkran holiday in April 2027. The new plan brings back part of the park sooner.

The Bangkok World buildings at the front of the park had limited damage because their floors are raised, according to the operator's managing director. Reports do not say when those buildings will open to visitors.

Why Siam Amazing Park Closed After Bangkok Flooding

Heavy rain that began on September 26, 2026 flooded parts of Bangkok, and floodwater covered almost all of Siam Amazing Park for 5 days. The park announced a 6-month closure on September 30, 2026.

The flood damaged rides, machinery, visitor areas, and the park's large artificial sea. The founder put the damage at no less than 500 million THB.

The park covers about 300 rai, or roughly 118 acres. It is also known for its large artificial sea, which Guinness World Records has recognized. You can read the earlier Siam Amazing Park closure update for the original reports.

What the Reopening Means for Your Bangkok Trip

If your trip falls before March 2027, expect a partly open park. Plan your visit around water activities instead of rides.

November to February is Bangkok's cooler, drier season, which suits a day outdoors in the water park zone. Mornings are an easier time for a visit because afternoons stay hot.

Reopening days can draw crowds, so a weekday visit may be easier than a weekend. If you are in the city in November, the Thailand festivals in November 2026 guide lists other events to fit around your plans.

What Visitors Should Check Before Going
