With songtaew you can comfortably look around in the area.
The dark-blue song-taew goes from Mae RamPhueng beach to Rayong Bus-terminal.
It is easy to get to Rayong or to Mae Raemphung with the blue buses, sometimes they come every half hour, sometimes every hour, sometimes not at all (cost 25 bath, you pay when you leave the “bus”)
In order to stop a songtaew, it’s just to wave, and they will stay and pick you up.
There is also a minibus from Ban Phe to Pattaya, as well as from Rayong bus-station to many other places, including Bangkok
