Aa mountain pass is a navigable route through a mountain range or over a ridge . Since mountain ranges can present formidable barriers to travel, passes have played a key role in trade, war, and both human and animal migration throughout history. At lower elevations it may be called a hill pass . A mountain pass is typically formed between two volcanic peaks or created by erosion from water or wind.
29-802: The Outeniqua Pass is a mountain pass in the Western Cape , South Africa , that carries the N9 / N12 national road through the Outeniqua Mountains north of George . It connects George and the Garden Route coastal plain with Oudtshoorn and the Little Karoo . It was constructed between 1943 and 1951, replacing the Montagu Pass as the main route from George to the interior. Mountain pass Mountain passes make use of
58-403: A gap , saddle , col or notch . A topographic saddle is analogous to the mathematical concept of a saddle surface , with a saddle point marking the minimum high point between two valleys and the lowest point along a ridge. On a topographic map , passes can be identified by contour lines with an hourglass shape, which indicates a low spot between two higher points. In the high mountains,
87-697: A bus or a shared taxi for sightseeing. Many bikers travel from Manali to Leh and other places in Ladakh on motorcycles, generally in a group. Earlier, there was no fuel station for 330 kilometres (210 mi) between Tandi and Karu. Now, a new fuel station at Keylong has become operational since September 2021. Motorists and bikers should fill up at the start of this stretch. Motorcycles and vehicles with small tanks should carry additional fuel in cans. In an emergency, fuel may be available at villages and campsites en route (Jispa, Zingzingbar, Sarchu, Pang, etc.), but this fuel may be adulterated and costly. At high altitudes,
116-502: A difference of 2,000 meters (6,600 ft) between the summit and the mountain is defined as a mountain pass. Passes are often found just above the source of a river , constituting a drainage divide . A pass may be very short, consisting of steep slopes to the top of the pass, or a valley many kilometers long, whose highest point might only be identifiable by surveying . Roads and railways have long been built through passes. Some high and rugged passes may have tunnels bored underneath
145-418: A dozen Bailey bridges and all of them are now being upgraded to two-lane steel bridges. The highway crosses many streams of ice-cold water from snow-capped mountains and glacial melts without a bridge and it requires driving skill to negotiate fast-flowing streams. The highway has many damaged stretches and under-maintained portions, where even a little rainfall can trigger dangerous landslides. The road quality
174-531: A nearby mountainside, as with the Eisenhower Tunnel bypassing Loveland Pass in the Rockies, to allow faster traffic flow throughout the year. The top of a pass is frequently the only flat ground in the area, and may be a high vantage point. In some cases this makes it a preferred site for buildings. If a national border follows the ridge of a mountain range, a pass over the mountains is typically on
203-786: A style of street racing which may take place on these roads. There are thousands of named passes around the world, some of which are well-known, such as the Khyber Pass close to the present-day Afghanistan-Pakistan border on the ancient Silk Road , the Great St. Bernard Pass at 2,473 metres (8,114 ft) in the Alps , the Chang La at 5,360 metres (17,590 ft), the Khardung La at 5,359 metres (17,582 ft) in Ladakh , India and

In the highest mountain range in the world, the Himalayas, passes are denoted by the suffix "La" in Tibetan, Ladhakhi, and several other regional languages. Examples are the Taglang La at 5,328 m (17,480 ft) on the Leh-Manali highway , and the Sia La at 5,589 m (18,337 ft) in the Eastern Karakoram range. Scotland has the Gaelic term bealach (anglicised "balloch"), while Wales has
261-476: Is at Sarchu . The 130 km drive from Zingzingbar to Pang is the toughest part of the journey on the highway and a nightmare at times. During the best of the season, without any blockades and traffic jams, it can take up to 5-6 hrs to cover this stretch with at least one halt en route. Almost 35 kms of stretch on either side of Sarchu has been double laned and is in good condition now. The 175 km long road from Pang to Leh via Morey plains and Taglang La,
290-498: Is in excellent condition and generally takes less than 5 hours to cover. Visiting some locations beyond Leh requires special permission, which can be obtained at Leh.

However, it is now possible to cover the entire journey from Manali to Leh in 14–16 hours in a single day, if there are no road blockades and traffic jams en route. The peak travel season is during May–June and September–October when tourists visit Atal tunnel, Rohtang pass, and Lahaul valley. Most of the domestic tourists return to Manali on
435-551: Is usually open for about six months a year from the first week of May when the snow is cleared from the highway to October when snowfall again blocks the high passes on the highway. Before the construction of the Atal tunnel, the highway used to remain closed beyond the Rohtang Pass during winter. With the completion of the proposed Shingo La Tunnel on an alternate route through Zanskar valley , targeted to be completed by 2025,

The roads at Mana Pass at 5,610 metres (18,410 ft) and Marsimik La at 5,582 metres (18,314 ft), on and near the China–India border respectively, appear to be world's two highest motorable passes. Khunjerab Pass between Pakistan and China at 4,693 metres (15,397 ft) is also a high-altitude motorable mountain pass. One of
493-471: The 473-km Manali-Leh road began serving as the second land approach to Ladakh. The average elevation of the Leh-Manali highway is more than 4,000 m (13,000 feet) and its highest elevation is 5,328 m (17,480 ft) at the Taglang La mountain pass. It is flanked by mountain ranges on both sides, featuring stunning sand and natural rock formations. The landscape changes after getting past
522-539: The Atal tunnel and the greenery starts receding upon entering the Chandra river valley in the Lahaul region that lies in the rain-shadow . After crossing Darcha , the greenery completely disappears and the mountain slopes on the leeward side become brown and arid. Most of the mountain peaks and highway Pass north of Darcha remain covered by snow even in summer and shine brightly in the sun. Adjacent glaciers melt (more so as
551-475: The air is thin and contains less oxygen. Acute mountain sickness is possible, whose symptoms include headache, nausea, dizziness, and vomiting. It can be fatal. A traveler arriving by air from lower terrain should acclimate to the high altitude by staying at least one night at the starting point (say, Manali), and plan to stay over at either Keylong , Jispa or Darcha before ascending to the highway's highest passes and plains after Darcha. Travelers should minimize
580-458: The border, and there may be a border control or customs station, and possibly a military post. For instance, Argentina and Chile share the world's third-longest international border , 5,300 kilometres (3,300 mi) long, which runs north–south along the Andes mountains and includes 42 mountain passes. On a road over a pass, it is customary to have a small roadside sign giving the name of

The state line
725-479: The pass and its elevation above mean sea level . Apart from offering relatively easy travel between valleys, passes also provide a route between two mountain tops with a minimum of descent. As a result, it is common for tracks to meet at a pass; this often makes them convenient routes even when travelling between a summit and the valley floor. Passes traditionally were places for trade routes, communications, cultural exchange, military expeditions etc. A typical example
754-489: The same day. Himachal Road Transport Corporation (HRTC) and Himachal Pradesh Tourism Development Corporation (HPTDC) operate buses that travel the entire highway in two days. Buses start from Manali at 4 am until 6 pm. The travel time from Manali to Keylong is now approximately 2 hours via the Atal tunnel. Private four-wheel drive taxis are available. Shared taxis are cheap as they charge per person, but they may be full of local residents. The tourist cannot stop either
