The last leg of Joanna Lumley’s journey takes her by dhow to Zanzibar, the spice island of Africa where merchants from around the world have left their mark on the architecture, religion and music. Finally, she travels to Jordan where the spice trail continued on land. She explores the vast plains of Wadi Rum from the back of a camel, meets one of the last nomadic Bedouin families and visits Za’atari refugee camp, home to Jordan’s newest arrivals. Her journey ends at the one of the great wonders of the world, the ancient city of Petra.
