The red light districts in cities are often labeled as places you should not go. Many assumptions are they are full of crime, drugs and are filthy. Red light districts are not just in one certain city, but can be found in many countries.
Famous red light districts can be found in London's Soho and Vancouver. The most famous red light district is in Amsterdam.
A red light district is an area where brothels and other generally illegal activities (like marijuana) are legal.
The most famous part of red light districts is the abundance of sex related activities. This includes live sex shows, strip shows, brothels and sex shops.
Not only are brothels legal in red light districts, but in some areas prostitution in general is legal.
One of the more unique stores in Amsterdam's red light district is a condom shop. The entire shop is full of condoms of all shapes, sizes and flavors.
