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

Answer

Perhaps a languages teacher could answer this better. However, "to travel around" suggests no fixed purpose or destination e.g. to just go from one country to another - France, Germany, Austria, Italy, etc.... "To travel across" is going in a straight horizontal line e.g. from France to Russia (and the countries in between). It's common to say "travel across the United States" - i.e. from East Coast to West Coast. (Whereas "travel around the United States" just suggests going to lots of different states.)

"Travel in Africa" - OK
"Travel inside Africa" - no!
"Travel around Africa" - good, see above
"Travel across Africa" - only if going e.g. East to West (or West to East!)

Hope this is helpful!
