Where Is Taiwan? Location, Size, Cities and Visa Rules

Taiwan lives more in headlines than in maps. Most first-time visitors arrive without a clear sense of where the island sits, how big it is, or how long they will be in the air to get there. This guide answers the questions travelers actually ask before booking.

We cover location, scale, airports, when to come, the major cities, languages, money and visas — and one reason a growing number of long-haul visitors now build a trip around Taiwan at all: preventive health screening, which starts at $299 here.

Where exactly is Taiwan?

Taiwan is an island in the West Pacific, positioned between Japan to the north and the Philippines to the south, with mainland China across the Taiwan Strait to the west. Its jurisdiction also covers the Penghu, Kinmen and Matsu archipelagos and numerous smaller islets.

Taiwan is in the northern hemisphere, north of the equator — its seasons run on the same calendar as North America, Europe and Japan, not the reversed one of Australia. The Tropic of Cancer crosses the island near Chiayi, in the south-central region, which is why the north is subtropical and the south is tropical. The island is shaped like a sweet potato, a name locals use for it (蕃薯 / fan-shǔ): long from north to south, narrow across the middle.

The official name is the Republic of China (ROC); internationally it is almost always called Taiwan. The capital is Taipei, in the north.

How big is Taiwan, and how many people live there?

Taiwan and its outlying islands cover about 36,197 square kilometers (roughly 14,000 square miles) — about the size of the Netherlands. The population is around 23 million, almost all of it on the western third of the island.

Most of that population lives on the western plain, because the interior is mountainous. Yushan (Jade Mountain) is the highest peak in East Asia, and roughly 20 percent of the country's land area is protected. So while the cities feel intensely urban, a national park, a hot-spring valley or a coastal cliff is never far away.

Which airport do you fly into?

Nearly all international travelers land at Taoyuan International Airport (TPE), which serves Taipei; Kaohsiung International (KHH) is the southern gateway.

From North America it is a single non-stop leg, and a long one — for most travelers it is the longest flight of their year. Block time moves with winds, routing and season, so read the duration off the airline's own schedule for the month you are flying rather than off a guide.

Taiwan's home carriers are EVA Air, China Airlines and the newer premium carrier STARLUX, and the transpacific map keeps changing. Why an island this size supports three long-haul airlines is its own story, told in this article.

Taiwan runs on a single time zone with no daylight saving, so the offset from your home city never shifts mid-trip. Our Taiwan time-zone guide has the arithmetic for each major source market, and the Taipei first-time visitor guide covers the first days on the ground.

When is the best time to visit Taiwan?

There is no single perfect month. The right window depends on whether you want hiking weather, beach weather, fewer crowds, or to avoid typhoons.

December to February (winter): Cool and dry in the south, cool and damp in the north. Taipei can feel raw in persistent drizzle; Kaohsiung and Tainan are genuinely pleasant. Best season for hot springs, food tours and indoor culture.
March to April (spring): One of the best windows — mild, cherry blossoms in the high country, no typhoons. Cherry season at Yangmingshan (Taipei) and Alishan (central) is a major draw.
May to June (plum-rain season): The "meiyu" front brings sustained rain, especially in the north. Hiking is harder; temples, museums and tea houses are at their best.
July to September (summer and typhoon season): Hot and humid, and the season when typhoons approach. Beach weather is excellent on the east coast and at Kenting, but check the Central Weather Administration forecast before you commit to an itinerary.
October to November (autumn): Many travelers' favorite — stable weather, lower humidity, vivid skies and a string of cultural festivals.

Our Taiwan weather guide breaks this down month by month and region by region.

Which cities will you actually visit?

Taiwan has six special municipalities. In order of population they are New Taipei, Taichung, Kaohsiung, Taipei, Taoyuan and Tainan — which surprises visitors who assume the capital is the biggest. Each has a distinct feel:

Taipei (north — capital): The political, cultural and culinary center, and the easiest base for a first trip. National Palace Museum, Taipei 101, Yangmingshan National Park, and a dense MRT network.
New Taipei City: The most populous municipality, wrapping around Taipei on three sides. Coastal Tamsui, the mountain villages of Jiufen and Pingxi, and Yehliu's geological park.
Taichung (central): Lower-density and more relaxed than Taipei, with strong arts and coffee scenes. Gateway to Sun Moon Lake, Lugang's old streets and the high-mountain tea regions.
Tainan (south — historical): Taiwan's oldest city and former capital. Temples, beef soup at dawn, and some of the most respected street food in Asia.
Kaohsiung (south — port): Taiwan's largest port. Warmer weather, wider boulevards, the Pier-2 Art Center, and quick access to Kenting National Park.
Hsinchu (north-central — tech corridor): Small but globally significant: Hsinchu Science Park anchors much of the world's chip industry. Increasingly a business-travel destination.

High Speed Rail runs the length of the west coast from Nangang in Taipei to Zuoying in Kaohsiung, which makes a two- or three-city trip easy to build.

How much English is spoken in Taiwan?

The official language is Mandarin Chinese, written in traditional characters — not the simplified characters used in mainland China. Taiwanese Hokkien (台語 / Tâi-gí) is the everyday home language for a large share of the population, especially in the south, and Hakka is widely spoken in Hsinchu, Miaoli and parts of Taoyuan. Taiwan also officially recognizes 16 Indigenous peoples, whose languages belong to the Austronesian family that stretches across the Pacific.

For English: signage at Taoyuan International Airport, Songshan Airport, Kaohsiung Airport and the entire Taipei MRT is bilingual and reliable. Major hotels, international hospitals, department stores and tourist attractions operate comfortably in English, as do most younger urban professionals. In smaller towns, traditional markets and rural areas, expect limited English — Google Translate's camera mode and offline Mandarin pack are genuinely useful there.

How do you pay for things in Taiwan?

The currency is the New Taiwan Dollar (NT$ / TWD). Payment methods, ranked by what you will actually use:

EasyCard / iPASS: contactless transit cards that also work at convenience stores, many cafes and some taxis. The single most useful thing to buy at the airport.
Credit cards: widely accepted at hotels, mid-range and high-end restaurants, department stores and chain retailers. Less consistent at small eateries and night-market stalls.
Mobile pay: LINE Pay and JKO Pay dominate domestically. Apple Pay and Google Pay work wherever the terminal takes contactless, but coverage is uneven.
Cash: still essential for night markets, breakfast shops, temples, small museums and rural travel. ATMs are everywhere; 7-Eleven and FamilyMart machines are the most reliable for foreign cards.

For connectivity, tourist eSIMs from Chunghwa Telecom, Taiwan Mobile and Far EasTone are sold at the airport and online, and the government's iTaiwan public Wi-Fi covers most transit and government locations.

Do you need a visa to visit Taiwan?

Usually not. Citizens of more than 62 countries and territories enter Taiwan visa-free for 14, 30 or 90 days. Most leisure travelers from major source markets show up at TPE, get stamped, and walk through.

The table below reflects the Bureau of Consular Affairs (BOCA) visa-exempt list as published on 17 July 2026. Confirm your own nationality on the BOCA page before booking — the lists change, and several entries carry an expiry date.

Duration of stay	Who qualifies (examples)
Up to 90 days	USA, Canada, UK (British Citizen passports), Ireland, all Schengen states, Australia, New Zealand, Japan, Republic of Korea, Israel, Chile, Paraguay, Guatemala, Honduras
Up to 30 days	Singapore, Malaysia, Belize, Dominican Republic, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines
Up to 14 days	Philippines, Thailand, Brunei, Oman (the first three currently effective until 31 July 2027)
Not visa-exempt	Everyone else — apply for an eVisa or a visitor visa through BOCA. Mainland China residents travel under a separate permit system.

Rules that apply to every visa-exempt traveler: your passport must have at least six months of validity remaining as of the date of entry; you need a confirmed onward or return ticket with a seat reservation; and the duration of stay is not extendable — it starts the day after you arrive, and you must leave by the end of it. Converting a visa-exempt stay into a visa-based one is only possible in narrow cases, such as serious illness or a natural disaster.

What does Taiwan's political status mean for a traveler?

Less than the headlines suggest. Taiwan governs itself, prints its own currency, runs its own immigration and customs, issues its own passports and sets its own foreign and economic policy. Most countries do not maintain formal diplomatic relations with Taipei but do run trade offices and de-facto embassies. For a tourist this means you arrive at TPE, get stamped through immigration on your home passport, and travel freely. No special permits, no extra paperwork, no questions at the border.

Taiwan and mainland China use different governments, currencies, entry rules and writing systems. A China visa does not work for Taiwan, and a Taiwan stamp does not work for the mainland.

What does a health screening in Taiwan cost?

This is the part of the trip we know best, and the reason a growing share of long-haul travelers add a screening to an existing itinerary rather than flying out specially.

Our lowest-priced screening is the Convenient holistic exam at $299: biometrics, a physical exam, blood analysis including advanced organ function and tumor markers, urine analysis, ECG, hearing and eye exams, chest X-ray and body composition, in about 90 minutes. It runs on Wednesdays and Thursdays only.

If imaging is what you came for, the Light package is $1,399 and covers a full-body MRI (head, neck, abdomen, pelvis and whole spine), a low-dose lung CT, and thyroid and abdomen ultrasounds, with a doctor's debrief in the same two-hour visit. Both are on our packages and prices page, alongside a-la-carte scans if you only want one thing.

Practical planning notes: a screening slot needs to be booked in advance, and the endoscopy add-on carries a 7-day flight restriction afterwards, so put it early in the trip and not the day before you fly home. We cover the mechanics in medical tourism for travelers, the money in the full-body checkup cost guide, and the imaging question in why many Americans now fly to Taiwan for a full-body MRI. Partner clinics are listed on our providers page.

Why do visitors keep coming back?

It is a serious business hub. Hsinchu Science Park anchors the global semiconductor supply chain. If you work in tech, hardware, manufacturing or finance, Taiwan is more relevant to you than most of your peers realize.
The food culture is dense and democratic. Some of the most respected food in Asia comes from a stall in a Tainan alley, not a tasting menu — though Taiwan has those too.
Nature is close. Taroko Gorge on the east coast and Yushan National Park in the central highlands are within day-trip or overnight reach of the big cities. The east-coast train ride from Taipei to Hualien is a destination in itself.
It is safe, late and walkable. Convenience stores on every corner, public transit that runs clean and on time. Many return travelers cite this — not the food, not the sights — as the real reason they came back.

You do not have to come for health screening. But if you were already coming, it is worth knowing the option is there — and that it costs less than the flight for most people reading this.

Frequently asked

Is Taiwan safe for tourists?

Yes. Taiwan is consistently ranked among the safest countries in Asia for travelers. Violent crime is low, public transit is clean and well-monitored, and convenience stores are open 24/7 across cities and most towns. Standard travel precautions still apply, but solo travel — including for women — is generally comfortable, even at night in major cities.

Do I need a visa to visit Taiwan?

Most travelers from the US, Canada, UK, EU/Schengen, Australia, New Zealand, Japan, South Korea and Singapore can enter visa-free for up to 90 days. Some nationalities get 30 or 14 days visa-free, and others can apply for an e-Visa online. The Bureau of Consular Affairs publishes the current visa-exempt list, and several entries carry an expiry date — confirm your own nationality there before booking, along with the passport validity it requires.

What is the best month to visit Taiwan?

October and November are the most popular months — stable weather, lower humidity, and the lowest typhoon risk. March and April are also excellent, especially for cherry blossoms in the high country. Avoid August and early September if you can, as those are peak typhoon weeks. Winter (December-February) is great for hot springs and food tours, especially in southern Taiwan where it stays mild.

Can I get by with English in Taiwan?

In airports, the Taipei MRT, major hotels, international hospitals, and most tourist sites — yes, very comfortably. Younger urban professionals in Taipei, Hsinchu, and Taichung generally have working English. In smaller towns, traditional markets, and with older shopkeepers, English drops off and a translation app becomes useful. Signage in major cities is bilingual.

How does Taiwan differ from China for travelers?

Taiwan and mainland China are governed separately, with different currencies, immigration systems, and even different writing systems (Taiwan uses traditional Chinese characters; the mainland uses simplified). A China visa does not work for Taiwan, and a Taiwan entry stamp does not work for the mainland. For travelers, the practical difference is that Taiwan has more relaxed entry rules for most Western and developed-economy passports, and an entirely separate booking and payment ecosystem.

Why do international visitors increasingly come to Taiwan for health screening?

Taiwan has built a strong reputation for high-quality, English-friendly preventive screening — full-body MRI, comprehensive blood panels, cardiovascular and cancer-marker packages — at well below US or UK prices, often with shorter wait times. Many international travelers now fold a screening day or two into a normal Taiwan holiday rather than making it the reason for the trip: our Convenient package is $299 and takes an hour and a half. You can browse screening packages and partner clinics for context.

What currency does Taiwan use, and are credit cards accepted?

Taiwan uses the New Taiwan Dollar (NT$ / TWD). Credit cards are widely accepted at hotels, mid-to-upscale restaurants, department stores and chain retailers. Cash is still important for night markets, traditional breakfast shops and small family-run eateries. ATMs at 7-Eleven and FamilyMart accept most foreign cards. The EasyCard contactless transit card is the single most useful purchase on arrival. For the current exchange rate and where to change money, see our Taiwan currency guide.
