Prachuap Khiri Khan is a relaxed seaside town. There is a nice hill to climb if you are not scared of monkeys. From the hill you have a stunning view of the bays and backlands. Although the main beaches of Prachuap are not good for sunbathing, there are 2 beaches just outside the city that made it to the TreasureBeaches site.
The southern part of thebeach is separated from the touristic main beach. It is a nice, quiet bay with a stunning view of a small island in the Upper Gulf region. Most people do not make it to this bay because you have to cross a small river or drive around the golf course.
