From Dubrovnik, I made a day trip on my final full day in Croatia to the country of Bosnia-Herzegovina. Since I did not have much time for mistakes and this involves a number of passport checkpoints, I decided to go with a tour.
It was only the previous week when temperatures peaked at around 40C, but in Mostar I mainly did a walk, a lunch at a rooftop cafe and then a dessert near one of the rivers. I did not swim at Kravica Waterfalls (no bathers, though I did spend much of the holidays debating if I should buy a new one), mainly sat near the edges.
Towards Mostar and back to Dubrovnik, the tour guide gave a LOT of information about history, culture, politics, society and more that I would not otherwise have gleaned, so it was a great experience overall.
City of Mostar
Mostar is quiet known due to its role in the war in Yugoslavia but it has some interesting cultural underpinnings to it. Unfortunately the tour guide we had focused on the war and seemed to not take his role seriously (making jokes, etc). I overheard another guide talking in greater depth and detail, but perhaps the quality that the other one is offering is higher due to a higher price.
While I was sitting down, I noticed or heard a group of three woman humming along in what seemed to be some sort of prayer.
