To get to Rayong, there are several choices available for visitors. Metered taxis from Bangkok are also available for the most convenient option, but pretty expensive though. Those, who stay in Thailand but far away from Rayong, can take a domestic flight to U-Tapao airport, an airport on the east, not far from both Rayong City and Chonburi City. Well, let see all those options in detail:
Minivan is what most visitors take to Rayong. (There is no bus from Bangkok to Rayong). Minivan from Bangkok, at the east terminal named Ekamai, are available more than Mochit Bus Terminal, every about 40 minutes, from early morning 4 AM till 10 PM (Approx. 140 Baht).
* In the case you are not familiar with Bangkok, to go to Ekkamai is much easier than Mochit 2 because you can get to Ekkamai Directly with BTS (Sky Train) and get off at Ekkamai Station, but to go to Mochit 2 you need to go to Chatuchak Station first and then catch a taxi or motorbyte taxi to go to mochit 2. Ekkamai also has public buses to Ban Phe.
To travel to Rayong by car is perhaps the most popular choices by Thai travelers, especially from visitors nearby and Bangkok. It not only is a quick and convenient way to travel to Rayong, but it is also a great chance to travel around the province of Rayong easily.
For foreign visitors, they can also do the same as native visitors by taking a rental car, available throughout the country, including Bangkok. However, they should study routes to go to and travel around Rayong, because of convenient and safety.
