I just want to know and tour, but many people tell me that several countries are very dangerous, a lot of African Guangue, what parents do you recommend me to visit? I love the cold and I want see the snow one day.
If you want cold, you can try the Scandinavia. Sweden is very dangerous (according to crime statistics). Norway is the exact opposite, very safe (insofar...). Norway doesn't belong in "Europe" (when it comes to paperwork, not placement), but she's in the Schengen contract (someone correct me if my info is wrong), so I would assume maybe similar rules apply to travel there as in other European countries (but you'll need a translator to read product labels as there's no option for English like with the European countries).
Germany is cold and has snow, as well.
I haven't been to France, but I've heard that Paris is very dirty and smells bad. But you can always visit smaller villages. I also know from many people's experiences that French people refuse to speak English... at least in Paris...
French have also come to my country and when I greeted them in English (saying a damn HI), they acted as if they didn't understand... I wanted to punch them.
Europe surely has many beautiful places to go to. Even if you visit one country, it's different to go to the capital, and different to go to a village or an island of that country. Many different choices. Of course, if you want to target cold countries, your options will be more limited, but still very beautiful.
As for the
African Guangue, well, being careful never hurts. If I were you, I'd check online police reports on crime for whichever country I wanted to visit. Always have your belongings close to you. Don't go in bad areas (areas that are filled with black people or that not many people walk by).
And of course, ask the locals. Ask them if there are any areas you should avoid, if there are dangerous areas nearby.
Like ModernMage said, situational awareness is also important to have. I remember when I was working at a tourist store, a tourist came to pay something, and I saw them searching for the right paper (of the amount I needed) with a green 100 euros paper in his wallet... that's a lot to carry around - even more so, to be so oblivious to it. So, I told him quietly that it's best not to carry that around because it may be stolen.
it never hurts to be careful.
