prepositions with the verb to travel
I don t know when to use preposition : across , around , in
If you want to go to different countries in Europe , I travel around Europe, is that right?
If you travel from one couuntry to another, I travel across Europe
So Could it have to do with having two fixed destinations or not?
And , would it be correct to say : travel in / inside Africa. ?
Any other preposition? Thanks
