South Pole

19th century explorers probed Antarctica's coasts but realized that the Pole lay over 1000 km inland in an intensely cold, uncharted region. The best route was from the Ross Sea, which ships could approach in summer. There you'd need to establish a base and lay supply caches along your return route, and camp over winter, to be ready to strike out for the Pole next spring and get back before the following winter overtook you. And how would you even know (and prove to the world) that you'd got there?

Several expeditions were forced back, the closest being Shackleton's Nimrod group of 1908 / 09 which got to within 180 km. This established that the interior beyond the Transantarctic Mountains was a featureless high-altitude plateau. Roald Amundsen (1872-1928) initially aimed for the North Pole, but this target was mired by contested claims of Peary and others to have reached it, and funding dried up. (Not until 1926 did Amundsen himself bring the first verified party to the North Pole, by airship.) He secretly switched focus to the South Pole and didn't even tell his crew until they'd left their last port-of-call in Madeira. They reached Antarctica in Jan 1911, camping on the edge of the Ross Sea ice shelf. They laid caches then in October set out with dog-hauled sleds along a straight line south, crossing the mountains by the Axel Heiberg Glacier, and reached the Pole on 14 Dec. They returned safely to the coast in Jan 1912. Just as they were doing so, Scott's Terra Nova expedition belatedly reached the Pole, to find Amundsen's tents and the Norwegian flag fluttering there. That group of five did not survive their return north.

No-one stepped foot on the Pole again until 1956, when a US Navy plane landed. Over the summer of 1956/57, the "International Geophysical Year", the US built a station that's been permanently staffed since. The next people to come overland, with limited air support, were Edmund Hillary and Vivian Fuchs, arriving separately in Jan 1958. The age of tourism began in 1987 with the opening of privately-run Patriot Hills airfield and camp, which in 2010/11 relocated to Union Glacier Camp, and this remains in use.

The climate at the South Pole is intensely cold, though it's not the coldest place on earth - that's in the vicinity of Vostok station at higher altitude. In December, mid-summer, the Pole averages −28 °C (−18 °F), and in July this drops to −80 °C (−112 °F). (There are no "day-time highs" or "night-time lows", since in summer it's always day and in winter it's always night.) The Pole is also very dry, and indeed is classed as desert. It seldom catches the furious "katabatic" winds that scourge the coast. However, it doesn't take much breeze to kick up the drifting snow into a blizzard white-out that will disorient then bury anyone caught out in it.

The area of interest is all within one km of the Pole along marked trails, so you get around on foot. Never leave these trails. There's simply nowhere else to go - the next point of interest is Kunlun station over 1000 km away, and frankly not worth the walk. This is a featureless plateau where conditions can turn from sparkling daylight to howling blizzard in an instant. The wind whips up the snow into a white-out where you have no sense of where you're going, and your trail gets covered so you can't retrace your route.

See Antarctica for general suggestions. The most important thing to do here is come home safe.

• The ceremonial South Pole is a metal sphere on a red and white pole, set within the flags of the signatories of the Antarctic Treaty. It makes a good photo but is about 300 m from the true Pole. (Yes, to be specific it's 300 metres north.)
• The Geographic South Pole is marked by a simpler rod. The ice here shifts 10 m annually and the marker is moved each New Year's Day in a small ceremony. There are also the US and Norwegian flags and a sign bearing quotes from the journals of Amundsen and Scott. Circumnavigate the world by taking a couple of dozen steps around the Pole.
• There have been three generations of station structures:
  • The Old Pole, the original wooden station, was built in 1956 and abandoned in 1975. It's now buried by drifting snow, and off-limits as unsafe.
  • The Geodesic Dome of the 1970s was dismantled in 2009 / 10 and its site soon became covered by snow.
  • The Elevated Station, built from 1999, is a modular structure on stilts to prevent snow from accumulating around it. Semicylindrical metal "arches" next to the dome serve as storage, power plant, and vehicle shop. They linked to the main station via a six-story unheated metal tower known as the "beer can".
• The Visitor Center is a grand name for a small tent.
• Station tours: you can but ask the staff, but the answer is usually "sorry".
• Play Disc Golf: this is the version where you flip a disc towards a target basket, playing your disc from wherever it lands. But it's odd that no golf course developer has sought to establish a traditional course and resort hotel here. Where's Donald Trump when you want him?
• Send a letter home from the world's southernmost post office in the station.

There is a small gift shop in the station, cash only.

Visitors are fed at the camp site, and can't access the station canteen.

• There's no shortage of fresh ice, but unlocking the water requires fuel and a means of heating. That's not a problem at the polar station and camp, but on treks such as "Ski the Last Degree" these add weight, and lugging them raises a thirst.
• As in any very cold climate, never drink alcohol until you are safely in shelter. It's notorious for generating a false glow of warmth and well-being while your core body temperature ebbs away.

Tourist visitors are accommodated at the campsite 1 kilometre (0.62 mi) from the station and Pole, using "Arctic Oven" tents.

All the health and safety advice for Antarctica apply in force to the Pole. The main local factor is that intense dry cold is combined with altitude, so you need to acclimatize. That's usually done by spending a night at a staging post such as Union Glacier. The UV is also stronger at this altitude.

Connectivity at the Pole is extremely limited. For around four hours each day, NASA satellites are in view which provide reasonably high-bandwidth connections; these are used for uploading scientific data and for staff to browse the Internet or have audio and video calls with family and friends. Another eight to nine hours of connection are available on two military satellites, at significantly lower speeds. The rest of the time, the only access is through the Iridium satellite network, which covers the entire globe and has excellent coverage at the poles, but only offers low-quality (and expensive) voice calls and dialup-speed Internet.

You're tied to your package itinerary, so you must return north with them. They may have the option of side-trips from their Antarctic staging post, e.g. from Union Glacier to Mount Vinson, or from McMurdo to climb the active volcano Erebus.
