Southeast Asia’s largest waterpark is about to get even bigger, after the US$46m (€38.6m, £34m) Ramayana Waterpark in Pattaya, Thailand, announced further investment plans in an effort to boost the region's tourism.

The waterpark celebrated its second anniversary on 5 May, having opened in 2016. Speaking to The Nation, Ramayana's director of marketing and sales, Johannes Patterman, confirmed the expansion plans, which will include investment in amusement facilities as well as organising events that cater to a larger number of tourists.

"The tourism industry of Pattaya, as well as of Thailand as a whole, is expected to grow continuously," he said.

"Pattaya’s tourism is also changing into a family destination with sports tourism, and this is good for the image of Pattaya. It also goes in harmony with the policies of the Thai government and Tourism Authority of Thailand of establishing Thailand as a family destination. The Ramayana Waterpark is ready to answer to this policy, and we are prepared to serve large organisations, group tours and families on a larger scale."

Since opening, the waterpark has received favourable reviews online, named best waterpark in Thailand by TripAdvisor, third best in Asia and 19th overall in the world.
