With Poland looking less likely to be open in the fall, I have turned my attention to Bosnia and Herzegovina for a 19-day trip. I'm in the early stages of planning and would love to hear recommendations on must-visit places, hidden gems, and any travel tips specific to Bosnia and Herzegovina. Also, if anyone has advice on the best time to visit, local customs I should be aware of, or any off-the-beaten-path experiences, that would be incredibly helpful. Looking forward to your insights!
