Adventure tourism in Ladakh started in the 19th century. By the turn of the 20th century, it was not uncommon for British officials to undertake the 14 stage trek from Srinagar to Leh as part of their annual leave. Agencies were set up in Srinagar and Shimla to specialise sport related activities — hunting, fishing and trekking. A large retinue of porters would carry huge canvas tents and collapsible string beds. This era is recorded in Arthur Neves The Tourist's Guide to Kashmir, Ladakh and Skardo, first published in 1911. Today, about 18,000 tourists visit Ladakh every year. Bounded by two mighty mountain ranges, it is a popular place for adventure tourism. The well-preserved Tibetan-Buddhist culture makes it even more attractive.
Transport
The main corridors for accessing the area 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 to October or November, when snow is cleared from the several passes. The Srinagar-Leh road is open from April or May to November or December, and is generally only blocked by snow through the winter at Zoji-La Pass. There is one airport, situated at Leh, from which there are multiple daily flights to Delhi on Jet Airways and Indian, and weekly flights to Srinagar.Tourist places

No special permit is required to visit most of Ladakh, including Leh and Kargil towns. Permits are required for both domestic and foreign tourists to visit the "Inner Line" areas, i.e. Nubra Valley; Panggong Lake and the Durbuk Block that it lies in (i.e. north of the Changla Pass); Tso-Moriri and Tsokar Lakes and the area along the Indus River east of Upshi; and Dha-hanu and the area along the Indus River northwest of Khalatse. These permits are easily available in Leh town from the local authorities and do not need to be acquired while applying for an Indian visa.Permits are not available, and foreigners are not allowed, in the far reaches of each of the above-named areas close to the borders (or Line of Control, etc) with Pakistan and China. For example, foreigners can go to the edge of Panggong Lake but not along the edge of it to Phobrang, Merak, Maan, or Chushul villages; they cannot proceed east up the Indus from the Mahe Bridge; and in Nubra, they can only go as far as Panamik to the north and Hundar to the west.
There are no border crossings open between Ladakh and neighbouring regions of Baltistan (under Pakistan) or Tibet (under China).
