The straight-line (great-circle) distance between Abu Dhabi (UAE) and Salalah (Oman) is approximately 225 miles (362 km). However, the practical travel distance varies dramatically by mode.
No direct road connects the two through the Empty Quarter (Rub' al Khali). Must travel:
Total: ~1,030 km, 11–12 hours driving. Requires Oman visa (if not GCC national), vehicle insurance, fuel planning (long stretches >200 km without services). Spectacular desert/mountain scenery (Jebel Samhan, wadis).
Salalah is Oman's southern gateway—monsoon (Khareef) turns it green Jun–Sep, attracting 500k+ Gulf tourists. Abu Dhabi–Salalah air corridor is a key intra-GCC leisure route. The Rub' al Khali barrier makes overland travel an expedition, not a commute.
