Travel in daylight for easier processing at borders. Your car must be in your name or you need GCC authorisation. Arrange comprehensive GCC car insurance in advance; border insurance is costly. Obtain a Saudi visa online where possible; first‑time visitors must do biometrics. UAE visa on arrival is straightforward but requires a short office visit. Expect detailed checks at Saudi borders, separate screening for women, and claim VAT refunds when exiting UAE if eligible.
