Road : Leh is connected to the rest of India by two high-altitude roads both of which are subject to landslides and neither of which are passable in winter when covered by deep snows. The National Highway 1D from Srinagar via Kargil is generally open longer. The Leh-Manali Highway can be troublesome due to very high passes and plateaus, and the lower but landslide-prone Rohtang Pass near Manali.
National Highway 1D : The overland approach to Ladakh from the Kashmir valley via the 434-km. Srinagar-Leh road typically remains open for traffic from June to October/November. The most dramatic part of this road journey is the ascent up the 3,505 m (11,500 ft.) high Zoji-la, a tortuous pass in the Great Himalayan Wall. The Jammu & Kashmir State Road Transport Corporation (JKSRTC) operates regular Deluxe and Ordinary bus services between Srinagar and Leh on this route with an overnight halt at Kargil. Taxis (cars and jeeps) are also available at Srinagar for the journey.
Leh-Manali Highway : Since 1989, the 473-km Manali-Leh road has been serving as the second land approach to Ladakh. Open for traffic from June to late October, this high road traverses the upland desert plateaux of Rupsho whose altitude ranges from 3,660 m to 4,570 m. There are a number of high passes en route among which the highest one, known as Tanglang La, is sometimes (but incorrectly) claimed to be the world’s second highest motorable pass at an altitude of 5,325 m. (17,469 feet). See the article on Khardung La for a discussion of the world's highest motorable passes.
Air : Leh's Leh Kushok Bakula Rimpochee Airport has flights to Delhi at least daily on Jet Airways and/or Indian Airlines and/or Air India which also provides twice weekly services to Jammu and a weekly flight to Srinagar. Connect in Delhi for other destinations. Go Air operates Delhi to Leh daily flights during peak time. Rail There are no railways currently in Ladakh, however a railway is proposed. See Bilaspur-Mandi-Leh Railway for more information.
