3. Explore the Kingdom of Saudi Arabia
Travel along the 25 tunnels road - a deeply dramatic road of tight hairpin bends that descends hundreds of metres in a short time, to the 600 year-old marble village of Thee Ain. The mysterious-looking set of stone houses, originally built as a citadel on top of a white marble outcrop, are surrounded by banana plantations, fruit trees and mountains. The 8th-century construction is visually magnificent from afar, and fascinating close up. We'll have a delicious al fresco lunch in a calm and shady spot, in the shadow of the mountain village.
