The town 25km from Rayong city is the port for ferries to Koh Samed, also known for fish processing.
There are several piers and if you get caught in the melee of sales desks apparently it’s easy to be stiffed for a speedboat to a beach you don’t want.
I find Nuanthip pier easier, 50 baht for big boat or 200 for speed boat, that’s a quid or 4. No discount for return so why bother and lose the ticket.
Nice local market type thingy behind the pier, but it’s Makro and Tesco for supplies.
There is a beach close to the piers, very quite. There ia a reason for that, it’s shite !
