[Grammar] Travel through/across

[angelene001]

Can you just confirm if I understand this correctly?
"To travel through Germany" means that you spend time exploring the country, visiting different cities.
"To travel across Germany" means that you, for example, drive from one border to the other only to get to the next country.

Not necessarily.

I travelled across (/through) Germany on my way to the Czech Republic.
I travelled through (/across) Germany last summer, spending time in Cologne, Franfurt,Würzburg, Nuremberg, Regensburg and Munich.

Context will probably make the implied meaning clear.

 

[angelene001]

When I've got an exercise and I have to complete the gap and I don't know the context, are both prepositions correct?

I travelled ........... China.
I travelled through/across China.

Similar problem with "the park".
I walked across the park.
or
I walked through the park.

When it comes to "the forest", I've thought there is only one option:
I walked through the forest.

Yes, your assumptions are all correct.
