Ladakh operates on a stricter calendar than most of India. Leh, its main town, sits at roughly 3,500 meters, and the high-altitude passes connecting it to the rest of the country are only open for part of the year. Getting the timing wrong here isn’t a minor inconvenience; it can mean roads are physically closed.
The Short Answer: May to September
Manali-Leh and Srinagar-Leh highways, the two main road routes into Ladakh, typically open sometime between May and June and close again by late September or October, depending on snowfall that year. Flights into Leh operate year-round, but road-trippers have a genuinely narrow window.
Within that window, June through August is peak season, coinciding with the most stable weather and school holiday travel from the rest of India. September offers thinner crowds with still-favorable conditions before the passes begin closing.
Winter: A Different, Harder Trip
Ladakh in winter (roughly November to February) is only accessible by air, since road routes close under snow. Temperatures regularly fall well below freezing, and this season is generally reserved for experienced travelers, notably those doing the Chadar Trek across the frozen Zanskar River, rather than first-time visitors.
Altitude Sickness Is the Real Planning Priority
Leh’s elevation means altitude sickness is a genuine risk, not a minor caveat. Most guidance recommends spending at least the first full day in Leh resting before any strenuous activity or travel to higher points like Khardung La or Pangong Lake, both of which sit at even greater elevation. Symptoms like headache, nausea, and breathlessness should be taken seriously, and descending is the standard response if symptoms worsen.
Permits: What to Know Before You Go
Certain areas near Ladakh’s international borders, including Nubra Valley, Pangong Lake, and Tso Moriri, require an Inner Line Permit for domestic and foreign travelers alike. These are generally arranged through registered travel agents or local authorities in Leh and are tied to specific dates and routes, so they need to be sorted before heading to these areas, not on arrival at a checkpoint.
What’s Worth the Trip
Pangong Lake, a high-altitude lake stretching into Tibet, and Nubra Valley, with its cold desert landscape and Bactrian camels, are Ladakh’s best-known draws beyond Leh itself. Magnetic Hill and the confluence of the Indus and Zanskar rivers are common stops along the way.
Bottom Line
If you’re driving in, plan for June through September and build acclimatization days into your itinerary from day one. If you’re flying in during winter, understand that this is a specialized trip, not a standard holiday, and requires cold-weather preparation most first-time travelers underestimate.
