Mostar was less satisfying. Great scenery. Excellent view from the mosque minaret, worth the small charge to get in. Bridge also quite appealing. Overall, though, the town has far too much of a “tourist trap” feel. I was there in late spring/early summer before the real tourist season begins in earnest. Would recommend avoiding unless you have keen interest in bridges, the Yugoslav war, or weird World War II paraphernalia/kitsch.

Not on this list, but I also recommend Vukovar. It’s in Croatia but directly across the river from Serbia. A must-see if you want to learn more about the war. Little or no tourist infrastructure, so be resourceful. Make it a day trip. I recommend visiting the hospital (Vesna Bosanac, who is something of a Croatian national hero, still works there.), the Catholic church, and the Ovcara killing fields.
