Leh is a region in the state of Jammu and Kashmir of Northern India sandwiched between the Karakoram mountain range to the north and the Himalayas to the south. The Indian portion of Ladakh is composed of the Leh and Kargil districts. The Leh district is the largest district of India, covering more than half the area of Jammu and Kashmir, of which it is the eastern part. The only two roads into the area from outside are the Zoji-La Pass and Kargil route from Srinagar in the Kashmir Valley, and the high altitude Manali-Leh Highway from Himachal Pradesh. The Manali-Leh road is open only from May or June to October or November, when snow is cleared from several passes. The Srinagar-Leh road is open from April or May to November or December, and is generally blocked by snow through the winter only at Zoji-La Pass.

Kushok Bakula Rinpoche Airport at Leh has flights from Delhi year-round on Jet Airways, GoAir and Air India. Air India also operates weekly flights to Jammu and Srinagar. Cancellations and delays for two or three days are not uncommon and can happen at any time of year, so travellers must plan for that possibility when scheduling their onward travel.Roads within Ladakh, except to Zangskar, are open all year round. Khardong-La Pass to Nubra has an alternate day schedule, is closed Mondays, and can get closed by snow for several days in winter and spring. Chang-La pass to Panggong Lake rarely closes, and if it does, rarely for more than one day.
