Dear Ljupco,
thank you for the compliments!
There is not a
waterpark in Halkidiki. Close to
Thessaloniki, near the airport, you will find "
Waterland" , the only
waterpark in northern Greece.
For in case you plan to visit Waterland, try to book your ticket at one of the available
excursion agents or go there yourself by
car (=cheaper!).
Depending on where you will stay in
Halkidiki, a trip to Waterland will take you approximately 1 hour.
