Por Vs A

Hicimos una visita por El Camp Nou.
• We went on a tour around The Camp Nou.

Hicimos una visita a El Camp Nou.
• We went on a tour to The Camp Nou.

Are both translations correct?

Many thanks in advance.

Yes.
The "por" only says you were nearby, "a" means the place was the destination.
