Europe is an incredibly diverse continent and has many beautiful cities. Many of those cities are perfectly set up for tourists, but some are considered more dangerous than others.
Crime in Amsterdam is largely concentrated in the nightlife districts and mainly involves pickpocketing at train stations and on public transport.
The most dangerous areas are around the East End, where there is often gang violence and drug dealing.
The areas around Les Halles, Châtelet-Les-Halles, and Gare du Nord can be particularly dangerous after dark.
While Madrid Spain is another city known to be generally safe for tourists, there have been reports of pickpocketing and muggings.
If you've visited Belgium, you'll know it's friendly with bustling cities like Brussels, though there have been reports of pickpocketing in the city center.
