Siam parks is one of the BEST waterparks

Its truly amazing and inexpensive. I reccomend visting the water park at least once. You can fast past to skip long ques on most rides all day for €18. Ive been on all of the rides. The best was the one that taken me underneath an shark tank full of real sharks and it was that high you had to go up 3 flights of stairs and you could see all the hotels and beach from it.
