1 guide, each rated 1 to 5 with the reason — and two lists per place, where you are comfortable and where to pay attention. Nowhere is called dangerous; the specific thing is what helps.
Watch for bikes — they have right of way and move fast. Don’t walk in bike lanes (marked in red).
Comfortable: Jordaan · De Pijp · Oud-West · Amsterdam Oost
De Wallen — the red-light district late at night, for drunk crowds and pickpockets
Anyone selling drugs in the street — it is not what they say it is, and this is where people are hurt
Bicycles, which are the genuine hazard: look right before stepping into a lane
The ratings are this site's own, from the guides' authors and the corrections readers send in; they are not an index. Read the general advice in travel safety tips.
