After breakfast, drive along NH-1 toward Leh. Cross Namika La (12,140 ft) and Fotu La (13,478 ft), the highest point on the Srinagar-Leh highway. Marvel at the dramatic lunar rock formations of Lamayuru (Moonland) and visit the historic 11th-century Lamayuru Monastery. Drive past the sheer cliffs of the Indus River gorge to reach the Indus & Zanskar River Confluence (Sangam at Nimmu), where the turquoise Indus merges with the muddy green Zanskar. Experience the optical illusion of Magnetic Hill, where vehicles appear to roll uphill against gravity, and visit Gurudwara Pathar Sahib, constructed and maintained by the Indian Army. Arrive in Leh (11,500 ft) by late afternoon. Check into your hotel, hydrate, and rest to aid high-altitude acclimatization. Dinner and overnight stay in Leh.
