Europe's special case: five-century Ottoman mosques, green mountains cut by turquoise rivers, and a people who greet Gulf visitors as family — all visa-free at some of the continent's kindest prices. Sarajevo's Baščaršija, the obligatory Mostar day trip, Vrelo Bosne and the Olympic mountains. Halal is near-default; seasonal direct flights ~5h; BAM ≈ 2.1 SAR; the Arabic-speaking driver-guide is the classic Gulf way around.
