When to Go
The Manali-Leh highway opens around mid-May and closes in October. The Srinagar-Leh highway is open slightly longer. July and August are peak months with all roads accessible.
Permits Required
Indian nationals need ILP (Inner Line Permit) for Nubra Valley, Pangong Lake, and Tso Moriri. Foreign nationals need RAP (Restricted Area Permit) additionally. Permits available online at lahdclehpermit.in.
Acclimatization is Critical
Leh sits at 3,500m. Spend your first two days in Leh without any trekking or driving to altitude. Stay hydrated, avoid alcohol, and eat light. Diamox can help prevent AMS.
What to Pack
Thermal layers, a good quality sleeping bag (even in summer), sunscreen SPF 50+, sunglasses, lip balm, and altitude sickness medicine (Diamox). Roads are rough — pack a first aid kit.
