evidence: I visited the charming city of Mostar on a day trip to Bosnia & Herzegovina from Dubrovnik, and I have to say, this place really took me by surprise. Nestled in the Herzegovina region along the Neretva River, Mostar gets its name from the iconic bridge spanning the river, the Stari Most. The drive from Dubrovnik was pleasant, but crossing the border was a bit tricky. We had to stop three times: first at Neum to enter Bosnia, then back into Croatia, and finally at Metkovic to enter Bosnia again. There’s a tiny sliver of Bosnia & Herzegovina that slices through Croatia, making for an interesting border-crossing experience.
