Do you think Antarctica is just penguins and icebergs? In fact, it's the coldest, driest, and most mysterious continent on Earth, hiding fun facts you may never have heard before! For many first-time travellers dreaming of visiting Antarctica, it remains both distant and fascinating. Covering over 13 million square kilometres — about 388 times the size of Taiwan — and holding 90% of the world's ice and 70% of its freshwater, Antarctica is a dream destination for many travellers and nature lovers. But do you know why Antarctic ice is blue? How time is calculated in Antarctica? Or why some say you don't need a visa to go there? This article has compiled seven little-known facts about Antarctica for you, covering everything from natural phenomena to common travel questions, offering a fresh perspective on this fantastical land at the end of the Earth. Whether you're planning a trip, doing your research, or simply curious, this article is well worth saving! 👉Further Reading: The Ultimate Guide to Antarctic Travel | In-Depth Antarctic Tours

You may have seen those jewel-blue photos of Antarctic icebergs and even wondered if they were photoshopped. But in fact, this dreamlike blue colour is exactly what Antarctic icebergs really look like. The bluer it is, the older and purer the iceberg. After years of compression, Antarctica's ice layers become extremely dense, with almost no air trapped inside. When sunlight penetrates these ice layers, short-wavelength blue light penetrates the deepest and is reflected back out, creating the blue colour we see with our eyes. This differs from white ice, which reflects scattered light, making it a stunning polar phenomenon shaped by natural optics. In comparison, Arctic glaciers, due to heavier snowfall and greater temperature fluctuations, tend to retain more air bubbles and impurities within their ice layers, causing the reflected colour to appear greyish-white, milky, or semi-transparent. As a result, Antarctic ice appears "bluer and more translucent" by comparison.

Setting foot on Antarctica yourself, you'll have the chance to see these legendary "blue icebergs" up close, glistening beneath a grey-blue sky — this isn't a movie special effect, but a miracle of colour that the Earth has compressed over time.

You might think Antarctica, covered in ice and snow, must be extremely humid. But the truth is quite the opposite — Antarctica is actually the driest place on Earth,with some areas even drier than the Sahara Desert. Antarctica's "Dry Valleys" region receives almost no precipitation, with an annual rainfall of less than 25 millimetres — lower than some parts of the Sahara Desert. The climate here is extremely cold, making it difficult for moisture to evaporate and form clouds, resulting in a very low chance of snowfall. Combined with strong winds that constantly blow away surface snow, the Dry Valleys have long stretches of exposed bare rock and dry glaciers, giving the landscape a "Martian surface" appearance. This is also why NASA has simulated Mars missions in the Antarctic Dry Valleys, even conducting extreme life experiments on microorganisms there. For scientists, this is one of the closest places on Earth to an alien environment.

Antarctica isn't just icebergs and penguins — it even has an active volcano and research stations operating year-round.Mount Erebus, located on Ross Island in Antarctica, is the southernmost active volcano on Earth. Its crater has held a lava lake for years and continues to release gases. Not far from the volcano, a research station established by the United States in Antarctica can house up to a thousand scientists and technicians. The base is equipped with heating, electricity, laboratories, and even Wi‑Fi. Imagine a row of low-lying buildings glowing with lights on a pure white ice field, with people typing away, holding meetings, and sending emails—this is the daily life at an Antarctic research station. Although travellers cannot enter the research stations, you'll hear guides on the cruise sharing these stories, revealing that "life in Antarctica" is far more human than you might think.

Antarctica has no cities, supermarkets, or permanent residents, but it's not an entirely deserted wilderness either. Every year, over 1,000 to 5,000 scientists and technicians from around the world take turns stationed at various Antarctic research stations, conducting observations on climate, geology, biology, and polar changes. These research stations are like small bases in the polar region, equipped with heating, canteens, storage warehouses, and even the ability to send emails and hold video conferences—true living laboratories for humanity in Earth's most extreme environment. Besides research teams from various countries, people from Hong Kong and Taiwan have also set foot on this icy continent. Hong Kong polar explorer Rebecca Lee first reached Antarctica back in 1985, and has since devoted herself to promoting environmental conservation and polar education. Taiwan's Professor Chen Pi-hsen took part in Antarctic neutrino observation research, making him one of the few Taiwanese scholars to have set foot on the polar continent. In recent years, more people have set foot on Antarctica through "travel exploration," just like our Antarctica In-Depth Tour Partner — renowned travel show host Chris Leung, who is not only a graduate in Ecology from Princeton University in the US, but has also journeyed to the polar regions multiple times. 📣 Want to hear Chris Leung's polar stories in person? 🔗Sign up now for the 【DeWonder Antarctica Online Experience Talk】: Click here to register

Did you know? Antarctica actually has no unified standard time. Since it spans all longitudes, it could theoretically belong to any time zone, but in practice it isn't assigned to any country's time zone system. So how is "time" calculated in Antarctica? It's actually quite simple—most tour routes and research stations directly adopt the time of their departure point to schedule daily activities. For example, on cruises departing from Ushuaia, Argentina, both onboard and onshore activities follow Argentina time (UTC‑3); some scientific bases from New Zealand or the US follow their home country's time for convenient communication with the outside world. So don't worry about "jet lag confusion" in Antarctica — just follow the itinerary schedule. Everything is designed according to local time (at the departure point), so you won't miss a single meal, island landing, or penguin-watching session! Common Antarctic Itinerary Time Zones

Most people picture penguins living in a frozen, snowy world, standing around in groups or sliding across the ice. But in fact, not all penguins live in Antarctica — some even live right at the equator! Take the Galápagos penguin as an example — it's the only penguin species in the world that lives near the equator, inhabiting the Galápagos Islands right on the equatorial line. These penguins cool themselves by stretching out their wings and staying in the shade; they're actually more afraid of heat than cold. That said, for penguin lovers, Antarctica remains the ultimate penguin stronghold — of the 17 penguin species in the world, 7 can be spotted on an Antarctic voyage, including Adélie penguins, Gentoo penguins, Chinstrap penguins, and Rockhopper penguins. Each species differs in size, movement, and call, making them the star attractions of polar travel! Sometimes you'll observe penguin processions up close during a landing, and sometimes you'll spot them leaping from ice floes into the sea from the cruise deck — it's no exaggeration to say that watching penguins alone is worth the trip to Antarctica. 👉 Further reading:Antarctic Penguin Watching Guide

Many people assume that since Antarctica doesn't belong to any country, no visa is needed. Although Antarctica does not have its own visa system, this doesn't mean you can just pack up and go. You still need to depart via countries such as Argentina or Chile, and comply with their local visa requirements. Common Departure Countries for Antarctic Trips vs Visa Requirements

💡Quick tip: To apply for Argentina's electronic travel authorization (AVE) from Taiwan, you must hold a passport valid for at least six more months, plus have entered the United States at least once in the past two years, or hold a valid US-issued entry permit (ESTA or B2/J/B1/O/P/E/H-1B visa) to be eligible

Having read this far, isn't Antarctica even more astonishing and down-to-earth than you imagined? Here are the seven key fun facts we've compiled for a quick recap:

• Why are icebergs blue? Because their extremely high density and near absence of air bubbles allow blue light to penetrate and reflect more easily
• Is Antarctica drier than the Sahara? Yes, the Antarctic Dry Valleys receive less than 25mm of precipitation a year
• Volcanoes and Wi-Fi? That's right, Antarctic research stations have power, heating, and even internet access
• Does anyone live in Antarctica? Around 1,000–5,000 scientists are stationed there short-term each year, carrying out various international scientific research missions
• No unified time zone? Antarctica spans every line of longitude, so itineraries are usually scheduled according to the departure country's time
• Do all penguins live in Antarctica? Wrong, some live near the equator! On an Antarctic trip you can spot as many as seven penguin species
• No visa needed? Antarctica itself requires no visa, but you must follow the visa rules of your departure point (Argentina/Chile)
