JEDDAH: British explorer Alice Morrison has become the first person to walk the entire length of Saudi Arabia from north to south, completing a 2,200 km journey entirely on foot. The 62-year-old from Edinburgh reached Najran on the Saudi-Yemen border at 10:30 a.m. on Dec. 15, concluding a 112-day expedition that began on Jan. 1. Accompanied by a specialist support team, Morrison crossed six provinces — Tabuk, Madinah, Makkah, Al-Baha, Aseer and Najran — passing through the UNESCO World Heritage sites of AlUla and Hima and traversing the Prince Mohammed bin Salman Royal Reserve.
