Entrance fee
For children under 90cm it is free. For people over 90cm they will charge you 300 Thai baht for the whole day.
Entertainment
At Grand Canyon Water Park there is the main bit if the Water Park which is very big and fun. there is a small place for the younger children. They even have zip lines which swing from one side to the other of the Water Park. From the Zip line you will see the whole view of Grand Canyon Water Park.

Food
You are not aloud to bring food into Grand Canyon Water Park. But you can buy tasty food and drinks for a good price.
