Mugging

When I was a teenager, I suffered my first and only mugging in my life. We were visiting Santiago de Compostela, which is a really beautiful city in the north of Spain. It’s also the end of the famous Santiago pilgrimmage route. Dozens of Many thousands of pilgrims walk this way every year and they come from everywhere of in the world.
Generally speaking Spain is quite safe concerning crime, and comparing compared to other countries. However, criminals tend to concentrate around touristic locations. Pickpockets, burglars, and thefts thieves find a good opportunity with tourists.
We were three young people and we were having lunch in an isolated park. Years afterward, I realize that in certain hours people who do nothing usually are usually in the parks. I also notice that the best way to show you are a foreigner person in a city is having lunch on the street. I know many people in the USA eat a sandwich or something else on the street, or a bank bench in a park but this is not very common in Spain (excepting for tourists). As a consequence we were honey surrounded by bees.
Immediately two people came to us to ask for money. They were nothing There wasn't anyone nearby to help us. I suppose we considered giving money was the best option. The problem is that you don’t know how violent are people are in front of you and a confrontation could be worse.
We were a bit shocked and extremely frustrated and upset. To be honest, they didn’t take a big amount of money but we felt absolutely angry.

Nice job Alvarez! My corrections are in red and my suggestions to sound more natural are in blue/grey.

Regarding "the north of Spain", we don't capitalise "north" because it doesn't form part of its proper name. So for example you would write:

He lives in the south of Spain

He lives in South Korea

A theft is the action of stealing something. A thief is the person who steals. So for example you could say "the thieves were convicted of the theft".

Worse is a comparison, whereas worst is a superlative. So for example:

"A confrontation could be worse" - you are comparing having a confrontation to not having a confrontation

"A confrontation could be the worst possible situation" - out of all the possible situations, a confrontation is the most undesirable.
