The weather in Thailand can be very hot. A little cooling is a welcome relief from time to time. Beside the islands and beaches Thailand has several water fun parks; swimming pools with artificial waves and huge water slides. These parks are sometimes combined with a normal theme park. Ideal to spend the day with children.
Santorini Water Fantasy is located North of Hua Hin.
Siam Park City in Bangkok is one of the older parks in Thailand. It is located in Mini Buri, eastern Bangkok. The park is combined with a normal theme park.
If you like to try surf boarding on artificial waves instead of the sea you can practice your surfing techniques at the Flow House in Bangkok.
