The Heart of Arabia Expedition is a two-stage 1,300km journey across Saudi Arabia, loosely following the route of the explorer Harry St John (Abdullah) Philby. Just as Philby did on his travels across Arabia, The Heart of Arabia Expedition will gather primary field data, supporting three specific areas of research. Our podcasts will enable you to follow our progress, learn about the endeavours and achievements of the explorer Philby, and discover the extraordinary beauty and diversity of Arabia.
