Bias but FC Köln is a great day.
To be honest any German club is goood. If you fly to Cologne, you’ve got with 2 hours on the train.
Koln - 3 sides, can catch multiple if you’re lucky.
Bayer Leverkusen
Schalke
Borussia Dortmund
Bochum
RW Essen
And less appealing Fortuna Düsseldorf, Borussia Monchengladbach.
Other than that of the big leagues, I’ve always loved a visit to Italy. If you stray off the big clubs like Milan and Inter (worth ticking off the San Siro, great ground), where there are tonnes of tourists you can get some great gems.
I’ve done Empoli (which was a personal favourite), which is Inbetween Pisa & Florence, Piacenza, Modena (amazing experience), Lazio, Milan and I’ve currently got a trip to Lecce booked for May.
If you don’t mind budget of the city Scandinavian ones are always good Copenhagen, Malmo, AIK, Brondby etc are all great, but just expensive when you’re there.
If you’re feeling particularly brave, Red Star a Belgrade is an interesting one, especially on a European night.
Since they’ve brought in the new rule In Europe you can almost plan your away trips for R16, last season I did Thursday Bayer04 Vs. Ferencvaros, then on the Friday I did Köln Vs. Bochum.
Sorry for the essay
