Many sites have categorized Curacao as a safe place to travel to.
Others see it as an unsafe place.
The truth is somewhere in between.
As a citizen of Curacao who has also lived for some long periods of time abroad, I can qualify Curacao as pretty safe. In the 12 years that I have lived here I have not been robbed not even once. Having lived before in Europe for 28 years I can count that I've been robbed of my passport in Paris, France, lost a couple of bikes due to robbery in Eindhoven, Netherlands and got a none complete delivery from a web shop more than once.
If we now compare statistics, I would say that I can say that my experience is that Curacao is very safe.
Of course, do not seek the unsafety, as with all cities, at a given time and a certain place. Don't go at night on your own anywhere, especially bad lit locations.
Travel safe to Curacao.
