That they are walking over the border suggests Turkey is not living up to its end of the migrant bargain of stopping migrants from entering Europe.
Police say a total of 168 Syrian refugees have crossed into Greece over its land border with Turkey.
Police say that while border crossings, over land or sea, are everyday occurrences what is unusual in this case is that the refugees are all families and that traffickers are not involved.
Police also announced on Saturday three illegal border crossings by undocumented migrants over the Turkish land border, including the case of a Bulgarian truck driver that hid 10 migrants, most from Iraq, in his truck.
