I want to travel to Rio de janeiro Brazil...?

Ok,to be sincere with you,you need always to watch your back.Your trip can be safe if you do these things. as soon as you land in the airport just use a taxi from the airport company,some of the taxis that will be there can be thieves and steal you while riding.Don't use jewels,it will attract thieves.don't trust anyone(women,children...) they can be thieves as well. But,Rio is a beautiful city that i'm sure you will enjoy it.
