Does anyone know if there are any close areas for swimming in this ports. I have already been in this ports but this time I'm bringing my little boy which is 2 years old and i don't want to go sightseeing.

Thanks for your answers.

For Katakolon, yes, there is a nice little beach area near town. For the other two, I can't say (I would doubt that there is anything close to the ship. Especially in Izmir as it is an industrial town/port area.
