Travelling both to Hua Hin from Bangkok, but also around Hua Hin attractions, is about to enter a new era under the banner of Event Hub @ Hua Hin Airport with testing of two different hop-on hop-off bus services now underway.
The first of these services is a tour bus experience departing from Siam Paragon, a major shopping mall in the Pathum Wan District of Bangkok, every Wednesday, Friday, Saturday and Sunday at 8.30 AM.

During trials the scenic route will include sightseeing opportunities at the Maeklong Railway Market about 80km outside the Bangkok city centre in Samut Songkhram. The proposed route then takes the coastal Naklua road passing the Ban Laem District of Phetchaburi Province and the salt fields of the largest sea salt producers in Thailand. Arrival time at destination Hua Hin is expected to be around 2.30 PM.
This is currently a very unappreciated regional scenic route with more information available by visiting https://royalcoastreview.com/2019/05/travelling-the-scenic-route-north-from-cha-am/

The second Event Hub bus will provide hop-on and hop-off services around Hua Hin from December, stopping at different attractions and hotels around Cha-Am and Hua Hin every Saturday and Sunday.
The routing details, pricing and other arrangements for both these services will be announced following the trial periods.
B-Concept Group’s founder and CEO William Kuipers, the parent company of Event Hub @ Hua Hin Airport, says Saturday and Sunday afternoon and evening markets with entertainment will commence at the Hua Hin Airport in 2022 with an opening date to be announced dependent on restriction reduction and public safety issues. This will include an annual calendar of consumer and travel fairs, concerts, corporate events, brand activation and festivals with top class food and beverage catering from Hua Hin hotels and restaurants.
There’s a multitude of plans to transform the currently functional airport into something quite different. See more at https://royalcoastreview.com/2021/10/the-phoenix-plan-at-hua-hin-airport-set-to-b-come-the-citys-event-hub/
