Full-day loop covering Magnetic Hill (photo/brief stop), Gurudwara Pathar Sahib and confluence (Indus & Zanskar). Roads are good; stops are short and scenic.
Drive to Khardung La (one of the world’s highest motorable passes) and descend to Diskit/Hunder in Nubra Valley. Road travel time ~4–6 hours with stops.
Short acclimatisation/photo stop at the pass (carry windproofs). Note that the pass is at high altitude—spend minimal time outside vehicle if symptomatic.
Transfer to airport/bus stand as per your scheduled departure. Aim to reach airport 1.5–2 hours before flight due to security and high-altitude procedures.
