"Social media users have constantly shared pictures of Da Lat being heavily flooded, which has encouraged tourists to change their plans and cancel hotel bookings," said Vu Anh Vu, owner of a hotel in Da Lat.

On June 23, many parts of Da Lat were heavily flooded following half an hour of heavy rain, felling trees and paralysing vehicles.

However, the weather in Da Lat has improved, but many social media users have continuously posted photos of flooded streets and heavy downpours on Facebook pages, leaving tourists confused.

At Vu’s hotel, his staff have constantly received calls from customers asking about the weather.

"We have to reassure customers and send them current pictures and videos of Da Lat to make them feel secure," Vu said.

In addition, some Facebook users have compiled images of heavy rains and flooding of Da Lat in the past years and then shared them widely on social media, leaving tourism business owners in dire straits because now is the peak summer travel season.

Da Lat, famous for its year-round cool climate and French colonial heritage, is a popular tourist destination in Vietnam
