Why go, and how to do it well

Perched on top of The Mall Bangkhae shopping center in western Bangkok, Fantasia Lagoon is a compact water park offering a practical and affordable way to beat the city heat. With water slides, a large pool for lounging, and food and drink vendors on site — including cold drinks and beer — it functions as a self-contained half-day destination, particularly well suited to families with children.

Entry is straightforward and budget-friendly, with adult tickets typically in the 200–250 THB range and reduced rates for children. The park is generally uncrowded compared to larger attractions, and visitors describe the facilities as clean and reasonably maintained, though some slides may be closed periodically for servicing. The atmosphere is relaxed rather than resort-like, making it a local favorite rather than a major tourist draw.

Good small water park for family. It is on the top of The Mall Bangkhae, the entrace fee is 220 THB for adult and 150 THB for child. There is some restaurant inside and cold drink,beer. If you rent swimming pool costume 70 THB per person. If you wanna go outside, Staff will stamp your hand, you are allowed to enter again and again. It was a good day with my family there.

Great place to take your family to. 3 of the themed slides were closed today because of renovation/service and will open soon. 200 bath for an adult and 150 for Kids,so its not much for a half a day with some fun in the water 😉. I would advice you to go in the weekdays as its not to many visitor aswell. You need a bathing cap to enter but you can rent it at the shop for 20 baths with other things as bathtube and swimmingboards. I would definitive come again 👍

Drove for an hour to get here with our child. What a huge waste of time and a disappointment! Very difficult to find in the first place. Then had to pay 250 thb entry and had to rent a swimmingcap. Our child could only use the slides for babies cause he is under 10, although he can swim very good. Most of the slides were closed and even the baby-slides were not all open. The slides he was allowed to use, we had to rent a tube for 80 thb as well. The slides are cracked, broken off and the walls are brown. The park is not maintained very well, the dressing rooms were also very dirty. They have a lot of staff sitting around, looking at their phone. Maybe they should let them clean a bit. Asking the full price with more than half the slides closed, doesn't feel very good. Also, there is no food or drink on the park. You have to get fully dressed again and walk through the shopping mall to get food. We got dressed and left after an hour of laying around in a babypool. NOT RECOMMENDED!
