====Highest points attainable by transportation====
* The '''highest point accessible'''
**'''by land vehicle''' is an elevation of {{cvt|6688|m|ft}} on [[Ojos del Salado]] in [[Chile]], which was reached by the Chilean duo of Gonzalo and Eduardo Canales Moya on 21 April 2007 with a modified [[Suzuki Samurai]], setting the high-altitude record for a four-wheeled vehicle.
** '''by road (dead end)''' is on a mining road to the summit of [[Aucanquilcha]] in [[Chile]], which reaches an elevation of {{cvt|6176|m|ft|0}}. It was once usable by 20-tonne mining trucks.<ref>{{cite journal |last=McIntyre |first=Loren |title=The High Andes |journal=National Geographic |volume=171 |issue=4 |pages=422–460 |publisher=National Geographic Society |date=April 1987 }} (includes description and photos of [[Aucanquilcha]] summit road and mine)</ref> The road is no longer usable. {{Coord|21.214|S|68.475|W|display=inline}}
** '''by road (mountain pass)''' is disputed; there are a number of competing claims for this title due to the definition of "motorable pass" (i.e. a surfaced road or one simply passable by a vehicle):
*** The '''highest [[asphalt concrete|asphalted]] road''' is the single-lane road to [[Umling La]], located {{cvt|17|km|mi}} west of [[Demchok, Ladakh|Demchok]] in [[Ladakh]], [[India]], which reaches {{cvt|5800|m|0}} ("19,300 feet" according to a [[Border Roads Organisation]] sign there that recognizes it as the "World's Highest Motorable Pass").<ref>{{Cite web |date=17 October 2017 |title=Battle for the Highest Motorable Road |url=https://www.motoroids.com/features/battle-for-the-highest-motorable-road-which-pass-takes-you-closest-to-the-stars/ |access-date=17 October 2017 |publisher=Motoroids |language=en}}</ref><ref>{{Cite AV media |title=China Border {{!}} Umling La Pass [ World's Highest Motorable Road ] {{!}} Ep-26 {{!}} Tripura to Ladakh Ride |url=https://www.youtube.com/watch?v=zpQQdyDU2EI |access-date=31 December 2022 |via=[[YouTube]]}}</ref> Before the asphalting of the road over Umling La, the highest asphalted road was [[Tibet Autonomous Region|Tibet]]'s [[Semo La]] pass at {{cvt|5565|m|0}}. It is used by trucks and buses regularly.<ref name="icc">{{Cite web| title = ICC – Semo Khardung| author = Assumpció Térmens| website = viewfinderpanoramas.org| publisher = Institut Cartogràfic de Catalunya| date = 20 March 2006| access-date = 5 February 2017| url = http://viewfinderpanoramas.org/ICCSemoKhardung.pdf| language = en}}</ref> The [[Ticlio]] pass, on the Central Road of Peru, is the highest surfaced road in the Americas, at an elevation of {{cvt|4818|m}}.
*** The '''highest unsurfaced road''' has several different claimants. All are unsurfaced or gravel roads including [[Mana Pass]], between India and [[Tibet]], which is crossed by a gravel road reaching {{cvt|5610|m|0}}. The heavily trafficked [[Khardung La]] in Ladakh lies at {{cvt|5359|m|0}}. A possibly motorable gravel road crosses [[Marsimik La]] in Ladakh at {{cvt|5582|m|0}}.
** '''by train''' is [[Tanggula Pass]], located on the [[Qinghai–Tibet Railway|Qinghai–Tibet (Qingzang) Railway]] in the [[Tanggula Mountains]] of Qinghai/Tibet, [[China]], at {{cvt|5072|m|0}}. The [[Tanggula railway station]] is the world's highest railway station at {{cvt|5068|m|0}}. Before the Qingzang Railway was built, the highest railway ran between [[Lima]] and [[Huancayo]] in Peru, reaching {{cvt|4829|m|0}} at [[Ticlio]].<ref name="highest_railway">{{cite web |title=Destination Guides – World's highest railway, Peru – Wanderlust Travel Magazine |last=Bennett |first=Suzy |publisher=Wanderlust Magazine |url=<!-- http://www.wanderlust.co.uk/article.php?page_id=510 -->http://www.wanderlust.co.uk/magazine/articles/destinations/a-train-journey-through-the-peruvian-andes |date=October 2003 |access-date=10 October 2008 |archive-url=https://web.archive.org/web/20110725012753/http://www.wanderlust.co.uk/magazine/articles/destinations/a-train-journey-through-the-peruvian-andes |archive-date=25 July 2011 |url-status=dead }}</ref>
** '''by oceangoing vessel''' is a segment of the [[Rhine–Main–Danube Canal]] between the [[Hilpoltstein]] and [[Neumarkt (district)|Bachhausen]] locks in [[Bavaria]], Germany. The locks artificially raise the surface level of the water in the canal to {{cvt|406|m|0}} above mean sea level, higher than any other [[lock (water navigation)|lock]] system in the world, making it the highest point currently accessible by oceangoing commercial watercraft.
