Why go, and how to do it well

Siam Amazing Park is closed. Floods in late September 2026 left nearly the whole park under water for five days, and on 30 September the owners announced a closure of at least six months, aiming to reopen before Songkran in April 2027. The founder has said the damage runs past ฿500 million and that the park could close for good without financial help, so treat any ticket offer you see online with suspicion until the park itself announces a date. Dream World, north of the city at Rangsit, is the theme park to go to in the meantime.

When it's running, this is the old Siam Park City, open since 1980 on Bangkok's eastern edge, with one pass covering the amusement rides and the water park. Weekdays can be so quiet you'll have rides to yourself, while weekends turn the same attractions into long, hot lines. The land rides are the stronger half, with a spread from baby-sized up to serious drops, so families with mixed ages don't have to split up. The wave pool is the famous part. Guinness certified it as the world's largest in 2009, though a pool in Abu Dhabi has taken the record since.

The park's own pages, for when it reopens, put the foreign adult pass at ฿1,000 and the children's pass at ฿850 for 101 to 130 cm, with under 101 cm free. Thai adults pay the same ฿1,000 and only the children's price is lower. Hours were 10:00 to 18:00, with the water park closing at 17:00. Tickets are non-refundable, and the park can close for bad weather without notice. It's at 203 Suan Siam Road in Khan Na Yao, and the nearest rail stop is Nopparat on the MRT Pink Line, exit 2, then a bus or motorbike taxi for the last stretch.

Starting from the negatives 1. being during every visit there’s almost guaranteed to be 1 to 3 rides closed for maintenance no matter what time you come 2. Avoid the weekends as each ride has very long queues Positives 1. There’s lots of rides for kids adults and families to try either separately or altogether all at once from big ones to medium size ones two baby size ones. 2. During the weekday this place is very empty so it’s best to come during the weekday as there’s no wait time 3 there’s lots of different foods available in Bangkok Road, which is also connected to the entrance Halal food for Muslims and Thai food for Thai people different cultural foods here 4. Getting here by taxi is very easy and the parking space is cheap and easy to find. 5. It’s very large so come here early as there’s a lot to explore even the map can get a bit. 6. It’s ฿1000 for adults but there’s a sale on for promotion right now so it was worth the price. 7. you can get tickets cheaper online or third-party 8. Great place for foreigners and tourist to come and try out, especially when it’s sunny. 9. It has three different sections, Bangkok world, Waterworld, and then the adventure world all are amazing. 10 . Staff speak enough English to make you understand rules 11. Machine, machines and instruction boards everywhere are in Thai and English good for foreigners. Overall, great experience I suggest to come during the weekday instead the weekend and if it’s on a sunny day, grateful for families and friends to come together or couples 8.5 out of 10 experience Only reason why I’m not giving you a 10 out of 10 is because from other reviews it seems like sometimes the big rides can be closed sometimes, but I got lucky this time and they were open Have fun visiting best of luck everyone

Siam Amazing Park is one of the most exciting and well-known theme parks in Thailand, offering a full day of fun for families, friends, and thrill seekers. The park has a great mix of attractions, including thrilling roller coasters, a huge water world, wave pools, and relaxing rides suitable for all ages. The grounds are clean and well maintained, and the staff is friendly and helpful throughout the visit. One of the highlights is the massive water park, which is perfect for cooling off in the tropical heat. The rides like the Super Spiral and Speed Slides add a lot of excitement, while the wave pool and lazy river give a more relaxing experience. The amusement park area also has classic rides, adrenaline-pumping roller coasters, and a fun atmosphere that keeps you entertained for hours. Siam Amazing Park offers good value for money, and there are plenty of food stalls and rest areas inside. Whether you want adventure, relaxation, or a great family outing, this park is a wonderful choice to enjoy a memorable day in Bangkok.

Fun for the family, but watch the budget!" "Siam Amazing Park is a Bangkok staple. While the ticket price is a little steep, you do get access to both the amusement park and the water park. The water side is a bit basic—don't expect a massive water kingdom—but it's okay for a few hours of splashing. The land rides are where the real fun is. Pro tip: Check for online deals or 'buffet inclusive' tickets to get better value for your money!" • The Wave Pool: It actually holds a Guinness World Record for being the largest in the world—definitely worth mentioning if you want to sound like a pro! • Value Hack: Many people find that booking through apps like Klook or Traveloka (especially in 2026) offers much better rates than the walk-in price.
