West Antarctica

From Wikivoyage
Jump to navigation Jump to search

West Antarctica is the region of Antarctica that falls in the Western Hemisphere.


There are many regions of Antarctica, some of which are mountains and some of which are flatter areas. However, these regions do not have their own articles because they offer few points of interest, let alone places to eat and sleep.

  • Ross Dependency is the portion of Antarctica claimed by New Zealand. Home to the largest Antarctic research station, McMurdo Station, and the world's southernmost active volcano, Mount Erebus.
  • Marie Byrd Land is the largest area in the world that isn't claimed by any country. This area is very empty even by Antarctic standards.
  • Chilean Antarctic Territory contains the entire Antarctic Peninsula and overlaps with Queen Elizabeth Land and Argentine Antarctica. It contains the Union Glacier Camp, which is a stopping point for most trips to the South Pole.
  • Queen Elizabeth Land is the U.K.'s claim to Antarctica. It also contains the entire Antarctic Peninsula and overlaps with the Chilean Antarctic Territory and Argentine Antarctica.
  • Argentine Antarctica is another Antarctic claim that overlaps with the Chilean Antarctic Territory and Queen Elizabeth Land.
  • Coats Land is closer to the Antarctic Peninsula than Marie Byrd Land.
  • Ellsworth Land is close to Vinson Massif.

  • 1 Belgrano II Base Belgrano II Base on Wikipedia (Argentina) The world's southernmost research station built on solid rock (not on ice) and is home to the world's southernmost church.
Halley Research Station
  • 2 Halley Research Station Halley Research Station on Wikipedia (U.K.) A research station that had been rebuilt 5 times and consists of 8 stringed modules. There are retractable gigantic skis on the bottom of the station, allowing it to be moved.
  • 3 Neumayer-Station III Neumayer-Station III on Wikipedia (Germany) A German research station on the Ekström Ice Shelf.
  • 4 SANAE IV SANAE IV on Wikipedia (South Africa) A South African research station consisting of 3 double-storied modules.

Other destinations[edit]

  • 1 Ellsworth Mountains Ellsworth Mountains on Wikipedia is home to Antarctica's highest point, Vinson Massif, at 4,892 m (16,050 ft).
  • 2 Thiel Mountains Thiel Mountains on Wikipedia is part of the Transantarctic Mountains. An aircraft fueling station for planes flying between the Union Glacier Camp and the Amundsen-Scott South Pole Station is nearby.
  • 3 Pensacola Mountains Pensacola Mountains on Wikipedia is a long range of mountains and is part of the Transantarctic Mountains.
  • 4 Queen Maud Mountains Queen Maud Mountains on Wikipedia is another part of the Transantarctic Mountains.
  • 5 Whitmore Mountains Whitmore Mountains on Wikipedia is also part of the Transantarctic Mountains and is in Marie Byrd Land.


The mainland of Antarctica is divided into two sides: the east and the west. While the Peninsula section of Antarctica is in the western portion of the continent, the Peninsula is not considered to be part of West Antarctica because it's a more popular tourist destination and has a climate not quite as extreme due to its location off the Antarctic Plateau, which East and West Antarctica sit on.

West Antarctica is the emptiest region of Antarctica, as there are only 4 permanent research stations here, compared to 17 in East Antarctica.


Due to West Antarctica's location on the Antarctic Plateau, most of this region lies at a high elevation, with ice miles deep. This means that what would already be a very cold area if it was at a low elevation is even colder. The high altitude, of course, brings health-related problems as well.


West Antarctica is mostly on the Antarctic Plateau, and the Transantarctic Mountains is mostly in West Antarctica. West Antarctica has a high altitude, which gets even higher when getting closer to the Transantarctic Mountains. However, the terrain is generally flat on most parts of the Antarctic Plateau.

Get in[edit]

This region is extremely difficult to get into, like East Antarctica. Unlike the Peninsula to the north, expedition ships generally avoid going to West Antarctica; the only exception to this would probably be the Ross Sea. However, a blue ice runway exists on Union Glacier Camp. This camp is privately owned and operated by Antarctic Logistics & Expeditions LLC (ALE). Chartered flights from Punta Arenas fly tourists to the camp and run trips to the interior of Antarctica including the South Pole, Vinson Massif and Hercules Inlet.

Get around[edit]

Like the rest of Antarctica, transportation within bases can be done on feet, and transportation out of bases should be done on skis and/or base transport.


  • 1 Bentley Subglacial Trench. The lowest point in the world not covered by oceans at 2,555 m (8,382 ft), although it is covered by ice.
  • 2 Mount Sidley. Antarctica's highest volcano (extinct), at a whopping 4,181 m (13,717 ft).


Summit of Vinson Massif
  • 1 Vinson Massif. The highest point in Antarctica, Vinson Massif (Mount Vinson) stands at 4,892 m (16,050 ft); climbs can be arranged by international travel agencies such as RMI and Adventure Consultants for some tens of thousands of dollars (US) per person, and take at least 14 days round trip from Punta Arenas. Aside from the weather and the absurd difficulties involved in transport there, the climb is supposed to be pretty easy, especially by "seven summits" standards. RMI: $43,600 Adventure Consultants: $43,000.
  • 2 Mount Tyree. This is one of the second seven summits; in other words, it's the second highest mountain peak in Antarctica. As of 2017, only 15 people had climbed to the top of Mount Tyree, so there are probably no tours to Mount Tyree.
  • 3 Antarctic Ice Marathon, . The annual Antarctic Ice Marathon is the start of the World Marathon Challenge (7 Marathons on 7 continents in 7 days). Racers will run 2 laps starting at the Union Glacier Camp. There is also a half-marathon option. $18900 for 2019 and 2020.


Like anywhere else in Antarctica, food will be served in bases, and must be carried when outside bases.


At most places in West Antarctica, there is ice covering the ground, so those with the ability to melt ice should not worry about water.


Unless someone at a base is willing for you to lodge, you will need to camp. Some excursions use Union Glacier Camp, a privately owned camp, as a base for their tourists.

Stay safe[edit]

Like the rest of Antarctica, West Antarctica is extremely cold and medical care is very limited. Medical insurances are strongly recommended and sometimes required.

Go next[edit]

  • The Antarctic Peninsula is the destination for any traveler who wants to say that they've visited Antarctica without having huge expenses. The peninsula in some ways more closely resembles some of the nearby Antarctic Islands than the Antarctic's interior.
  • East Antarctica is the other side of the continent.
  • The South Pole isn't part of either East Antarctica or West Antarctica, of course, but is adjacent to both sides of the southernmost continent.

This region travel guide to West Antarctica is a usable article. It gives a good overview of the region, its sights, and how to get in, as well as links to the main destinations, whose articles are similarly well developed. An adventurous person could use this article, but please feel free to improve it by editing the page.
