Many women travel alone in Greece. The crime rate remains relatively low and solo travel is probably safer than in most European countries. This does not mean that you should be lulled into complacency; bag snatching and sexual assault do occur, particularly at party resorts on the islands.
The biggest nuisance to foreign women travelling alone is the guys the Greeks have nicknamed kamaki. The word means 'fishing trident' and refers to the kamaki’s favourite pastime: 'fishing' for foreign women. You'll find them wherever there are lots of tourists: young (for the most part), smooth-talking guys who aren't in the least bashful about approaching women in the street. They can be very persistent, but they are usually a hassle rather than a threat. The majority of Greek men treat foreign women with respect.
