Search for the world’s highest bikeable roads is mainly characterized by indefinable actual
altitudes of respective roads. Relevant literature, maps and information on the internet
provide many thousands of (often questionable and conflicting) results. While findings
regarding the highest roads in Europe and North America can be verified by many sources the
situation concerning the rest of the world differs totally. In particular, in the Himalayas and
the Andes new roads are constantly under construction and actual trafficability of such roads
is subject to changes of political and climate conditions in these areas.
Besides the Himalayas the South American Atacama Desert in the border area of Bolivia and
Chile is the area with highest roads in the world. In the past such roads were built to reach
sulphur mines in an elevation of more than 5,000 meters. In recent times new astronomical
observatories have been established in the Atacama Desert including runways leading to the
facilities in respective altitudes.
Barometric altimeters do only provide reliable results if they have previously been calibrated
and if weather conditions stay unchanged. In particular, the accurate calibration can become
quite difficult in remote areas of the Andes or the Himalayas. However, even GPS has a
weakness and provides incorrect results if in dead spots only three (and not the necessary
four) satellites are available for measurement. In this case the global position can be
determined exactly but you can not rely on the reported elevation. Anyhow, interaction of
GPS and barometric altitude data in numerous travel reports, the contour lines in Google
Maps and the elevation data in Google Earth provide a reasonably reliable picture of the
actual situation. In any case the fundamental question is whether a route is uphill passable on
a bicycle, at all. Of course, you can partly ride, push and carry your bike cross country and
thus reach any mountain peak. This may even lead in some cases to reported heights of more
than 6,000 meters in Bolivia, Ladakh/India or at the Ojos del Salado/Chile. Several elevation world records on a mountain bike have been established at the latter volcano.
Some adventurers even carried their mountain bikes through deep snow up to altitudes of more than 7,000 meters in the Pamirs at Pik Lenin and Muztagh Ata.
However, present search for the highest roads follows the simple idea that a road is continuously uphill bikeable
if also a motorized two-lane vehicle finds its way on a route designated for that purpose - but actually even those runways are not always cyclable!
Asia
Finding the highest mountain road in Asia may also mean discovering the highest road in the
world. The title “Highest motorable road in the world” is currently still claimed by the Khardung La (5,602 meters / 18,380 ft) in Ladakh/Indian Himalayas. This information can be
found on site and is repeated countless times in several travelogues. However, there is
a catch in it: On the one hand you can occasionally find information on even higher mountain
roads and on the other hand the reported elevation of 5,602 meters is obviously wrong
anyway. Actual altitude of that pass likely seems to be only some 5,360 meters. Latter
specification can be found in an increasing number of trip reports, is meanwhile also being
reported by Wikipedia and is consistent with the Google Maps/Earth altitude indication.
Moreover, the popular Nelles Map of “North India” shows in Ladakh passes with its peak at
even higher altitude: Sia La is reported at 6,200 meters and Khurdopin La at 5,790 meters.
While the Sia La elevation is indicated in other sources with only 5,589 meters the Khurdopin
La elevation might be correct. However, reports and photos on the internet show that both
passes are apparently only trekking paths and are not rideable on a bicycle.
A further mentionable pass road in Ladakh is located some 100 kilometers east of Leh. Respective elevation figures
of Marsimik La vary in different sources between 5,582 and 5,680 meters. Satellite images report an altitude of some 5,640 meters/18,505 ft
and pictures on the internet show that this pass is accessible by 4WD all-terrain vehicles and motocross bikes.
However, the dirt track is reported to consist of loose sand and access is said to be prohibited to foreign nationals
as the pass is located near the cease fire line between India and China. Thus, only very rare reports about cycling the Marsimik La are available so far.
Due to the obviously wrong altitude of Khardung La other passes and neighboring runways at Siachen
Glacier in the Karakoram/Himalayas and on the Tibetan plateau with their peaks beyond
5,500 meters come into consideration as being highest rideable roads in the world. At
militarily strategic Siachen Glacier Google Maps shows a road from the Chinese side up to
Karakoram Pass (mostly reported with 5,575 meters / 18,291 ft). Google Maps also indicates
an elevation of more than 5,500 meters. However, the three nuclear powers China, India and
Pakistan show heavily armed military presence at Siachen Glacier and information about the
military blocked roads is hardly available. Thus, this area is actually not attainable for
ordinary cyclists. If you are weary of life you may try it…
Increasing number of reports name in Tibet the Semo La (5,565 meters / 18,259 ft) and the
Suge La (mostly indicated with 5,430 meters / 17,816 ft) as candidates for being the highest
rideable roads in the world. Likewise Khardung La in Ladakh the traverse of Suge La has
meanwhile become part of professionally operated mountain bike tours in that area (on the
Lhasa-Kathmandu route). Google Earth/Maps confirms the elevation of Suge La above 5,500
meters. Even higher seems the peak of Semo La on northern ancillary road from Lhasa to the
West (in direction to Mount Kailash). Reported GPS measurement has allegedly indicated an
altitude of 5,565 meters and Google Maps/Earth again confirms an elevation above 5,500
meters. However, this pass is only a little hump on the Tibetan plateau which stretches
constantly over hundreds of kilometers on an altitude level above 5,000 meters. With due
respect to all cyclists traveling there, but this does not seem to be an uphill-ride but rather
an onhill-ride (after all it is very respectable to get with a bicycle on the Tibetan plateau
previously). Anyhow, given facts argue for Semo La being currently the highest actually
accessible spot for cyclists in Asia!
For purists to note is that Karakoram Highway from Pakistan to China is supposed to be
continuously asphalted and it should be possible in theory to ride the highway on a road bike
up the Khunjerab Pass (4,733 meters / 15,529 ft). However, photos and reports on the
internet show that the road is severely exposed to weather conditions and that a 23
millimeter bicycle tire is not advisable on that trip. (And Pakistan currently does not seem to
be a very cozy area, anyhow…) In Ladakh/India the main road from Manali to Leh up to Taglang La (5,358 meters / 17,580 ft)
is asphalted on its southern ramp up to an elevation of 5,000 meters but then becomes an
unpaved dirt road which is no longer rideable on a road bike.
South America
In the South American Andes the situation is similarly confusing like in the Himalayas. Many
high altitude gravel roads are particularly being reported in Bolivia and Chile. But all
elevation indications vary greatly in different reports and you can actually not rely on them.
However, actual elevation of the unpaved dead-end road in La Paz/Bolivia up to the former
ski area to Refugio Chacaltaya (5,200 meters / 17,061 ft) can be verified. This elevation is
Google Maps/Earth confirmed.
Even higher spots can be found on the plateau of Chilean Atacama desert, driest desert in the
world. Due to the climate conditions in that stone desert several astronomical observatories
have been erected there in the past. The Atacama Large Millimeter/submillimeter Array (ALMA) site with its several astronomical facilities is located there. On Cerro Chajnantor at an elevation of 5,612 meters / 18,412 ft several universities currently construct the Cornell Caltech Atacama Telescope (CCAT).
And another observatory has already been built there by the University of Tokyo. However, the whole area is non-public and access is ALMA-controlled and only from 2013 onwards a visitor center will be available at the ALMA site. Satellite images and photographs on the CCAT-website clearly show a trafficable runway up to the facility.
But a fence actually blocks the road and thus the road is currently
not rideable for ordinary cyclists. Nearby at Cerro Sairecabur another mobile Receiver Lab
Telescope can be found at an altitude of 5,525 meters / 18,127 ft. This observatory and the
respective road up there can also be clearly identified on satellite images. Pictures on scientific websites providing information on that
observatory show 4x4 cars next to the facility and the satellite images even show that the
road continues up to an elevation of more than 5,600 meters. Runways to both observatories
have their peaks at higher altitudes than respective Himalayan roads supposed to be the
highest roads in the world and both runways seem in theory to be cyclable. However, the
plateau of Atacama Desert has very hostile climate conditions (NASA is supposed to test its
Mars cells there) and next domiciled location San Pedro de Atacama is some 70 and 100
kilometers away, respectively. Actual access to these roads is nebulous and at Cerro
Sairecabur mine fields are being reported. Accordingly, these spots are currently hardly
accessible by cyclists.
In the southwest of Bolivia volcano Cerro Uturuncu is located with its summit at an altitude
of more than 6,000 meters and an old mine road leading up there. However, travelogues
report very different information about the trafficability of that runway. All reports agree
that the road is only rideable up to a few hundred altitude meters below the summit. Respective
information varies from 5,200 meters to 5,900 meters. As the old mine is no longer in
operation the road is meanwhile blocked up by landslides. Satellite images clearly show the
interrupted runway leading to an elevation of some 5,700 meters. Local guides confirm that the road was accessible "up to the saddle" (i.e. 5,700 meters) by a 4WD in 2010 und in spring 2011. But they also report that the runway is not bikeable and the few cyclist riding there all have to push their bikes.
Very similar is the situation
at Chilean volcano Aucanquilcha. In the past there was a sulphur mine at an altitude above
5,600 meters and a dead-end road was leading up there. But now this runway is reported to
be partly blocked and can not be cycled anymore.
Highest paved road in South America (likewise in the world) is supposed to be Ticlio-Pass/Abra Anticona (4,818 meters / 15,808 ft) east of Lima in Peru. However, there seems
to be an even higher cleanly asphalted route also in Peru: The road from Chivay to Arequipa
has its peak apparently at 4,910 meters / 16,110 ft. Photos on the internet show the
nameless pass summit with a stone sign indicating this altitude and Google Earth/Maps
confirms an elevation of some 4,860 meters – higher than Ticlio-Pass!
North America
In the Rocky Mountains in Colorado/USA you can find two adjacent peaks that have ever been
competing for tourists and visitors and that are both accessible on a bicycle: Mount Evans
(4,307 meters / 14,131 ft) and Pikes Peak (4,301 meters / 14,112 ft). While the road up to
Mount Evans is continuously paved and thus rideable on a road bike the runway up to Pikes Peak is only partly asphalted but mostly unpaved. However, the private toll road is generally
closed to bicycles. Only once a year (in late August) cyclists are permitted to climb Pikes
Peak.
Europe
Europe knows world-famous pass roads in the Alps being tackled every year by thousands of
amateur cyclists. However, the highest accessible spot in Europe is not located in the Alps but
in the Spanish Sierra Nevada. A cleanly paved road from Granada winds up to the peak of Pico
del Veleta (3,394 meters / 11,136 ft) and can be challenged on a road bike. The southern
ramp of the pass is only an unsealed path and respective travelogues indicate that it may
even be hard to ride this part on a mountain bike. Mountain bikers may rather search for their
highest accessible runways in the Alps: However, dead-end road up to the Italian Bontadini ski-lift (3,332 meters / 10,955 ft) and to even higher close-by spots at Theodulpass is actually not continuously rideable by bicycle. The same applies to the way to French/Italian
Mont Chaberton (3,136m) or to French Glacier de Mont de Lans (some 3,160 meters / 10,368 ft). But Italian Colle Sommeiller (3,030m / 9,962 ft) is said to be accessible. And at Italian Madritschjoch and Swiss Gornergrat an elevation of more than 3,000 meters can also be reached on narrow tracks. Possibly the dirt road up to the Russian observatory
Terskol (also some 3,100 meters / 10,171 ft) in the North Caucasus close to Mount Elbrus
may even be the highest unpaved road in Europe.
Africa
Highest roads in Africa should be found either in Morocco, in the mountainous East Africa
(Ethiopia, Kenya, Uganda, Tanzania) or in the Drakensberg Mountains in South Africa/Lesotho.
As some of these areas are still not well developed but Third World countries it is hard to
obtain reliable information about the condition and elevation of mountain roads there.
In Ethiopian Highlands there are several unpaved roads with their peaks at an elevation of more than 3,000 meters.
Near Mount Buahit in the Simien Mountains you can even find a runway with its highest point above 4,000 meters.
However, the road on Sanetti Plateau in the Bale Mountains National Park is even higher:
A dead-end side road leads to a telecommunication device on the summit of Mount Tullu Deemtu (4,377m / 14,361ft), one of the highest peaks of the country.
The road is clearly visible on satellite images and is apparently accessible by bicycle.
South African Drakensberg Mountains have their highest summits in embedded Lesotho. There you
can find a paved road through the country with its peak at Tlaeeng Pass (3,251 meters /
10,666 ft). Pictures on the internet show this pass with an asphalted road and the respective
altitude indication. Google Maps/Earth confirms this elevation. The way from South Africa to
Lesotho leads via Sani Pass (2,873 meters / 9,426 ft) and Kotisephola Pass/Black
Mountain Pass (3,240 meters / 10,630 ft) both obviously being only graveled runways.
At Mount Kilimanjaro in Tanzania you could theoretically ride on a mountain bike on Marangu
route up to Kibo Hut (4,700 meters). Unfortunately, the National Park is completely closed to
cyclists. Thus, you can only ride on a paved road (with murderous motorized traffic) up to
Marangu Gate at some 1,900 meters.
Oceania
Provided Hawai'i belongs geographically to Oceania the partly graveled road up to the
observatory at Mauna Kea volcano (4,200 meters / 13,808 ft) should be the highest bikeable
road on the continent.
Face-to-face with Mauna Kea another volcano is located: Mauna Loa has an observatory at its
Northern side at an elevation of 3,397 meters/11,169 ft. This facility is actually accessible
on a narrow but asphalted runway leading through solidified lava up to the observatory.
Otherwise the road up to the ski resort Charlotte Pass (1,840 meters / 6,037 ft) close to
Mount Kosciuszko in Australia should be named the highest road of the continent rideable on a road bike. Whether there are even higher roads in New Zealand or in New Guinea is unknown,
but unlikely anyhow.
