Which deserts and mountain regions did Marco Polo cross on his journey to China?

During his journey to China, Marco Polo traversed several challenging landscapes, including arid deserts and high mountain ranges:

• Deserts: After leaving Tabriz, the travelers crossed inhospitable, brigand-infested deserts to reach Hormuz. They later traveled through regions of "surpassing aridity" toward Khorasan. Upon entering the Uygur Autonomous Region of Xinjiang, they followed routes along the oases south and east of the Takla Makan Desert.1
• Mountain Regions: Marco Polo visited areas in the Hindu Kush and potentially Kashmir while staying in Badakhshān. Subsequently, the party crossed the Pamirs, a high-altitude Central Asian mountain chain, before descending toward the borders of China.1

These arduous travels were essential to his arrival at the Mongol court in 1275.1
