Is Amsterdam safe to travel? Yes, it is. The Safe City Index 2015 Amsterdam gave it the 5th position in the list of safest cities in the world. Though it has a rock and roll- character, with its tolerance of marihuana and truffles and prostitution, Amsterdam is not a dangerous city. The city does especially well in regards to traffic. Although everyone travels by bike, there are not many traffic accidents and the air in Amsterdam is not (much) polluted.
Considering crime, Amsterdam is also relatively safe. The risk of violent assault in Amsterdam is pretty much absent, in all parts of the city. Also, crime rates in general in Amsterdam are going down every year.
Still, most of the crimes like robbing and pickpocketing in Amsterdam happen to tourists, especially in the Red Light District. Tourists are more often targeted than Amsterdam residents because they are easily distracted. Tourists will need to be careful of petty thieves, like pickpockets and getting your bag, jacket or things from your car stolen. Also always ignore the street dealers you can find them at nighttime!
The biggest crime in Amsterdam is tax evasion but that won’t bother you! Bike theft may be risky, so always lock your bike to a fence!
