Before you fly
Tainan's own airport, Tainan Airport (TNN), serves domestic and a limited set of routes, so many international visitors arrive via Taipei's Taoyuan International Airport (TPE) or Kaohsiung International Airport (KHH) and then travel onward by high-speed rail or regular train. Decide which entry point fits your route before booking, since the onward travel time and cost differ depending on where you land.
Check Taiwan's current visa and entry requirements for your passport before you book, since these depend on your nationality and change over time — this isn't something to assume based on a general impression of Taiwan being easy to visit. If you plan to use a local SIM or eSIM, sorting that out before or immediately on arrival will make everything else in this guide — maps, transit apps, translation — easier from the first hour.
On arrival
If you fly into Taoyuan or Kaohsiung and continue to Tainan by rail, Taiwan's High Speed Rail (THSR) connects southern Taiwan quickly, with a THSR station a short distance outside central Tainan requiring a local transfer into the old city center. Regular rail service also runs directly into Tainan's main train station, which sits closer to the historic core. Confirm current connection times and transfer options on the operator's own booking page, since schedules and connecting shuttle services can change.
Taiwan drives on the right, and Tainan has notably heavy scooter traffic even by Taiwanese standards. If you're not used to sharing the road with a large volume of scooters as a pedestrian or driver, take an extra beat at crossings, especially where scooters filter through turns.
First 24 hours
Resist the urge to plan your first day around a list of named attractions. Tainan rewards wandering between temples, old streets, and food stalls more than it rewards a tight schedule, partly because a lot of what makes it distinctive — smaller shrines tucked into residential streets, a stall with no sign that's been running for decades — doesn't show up neatly on a map.
Spend part of your first day near the historic core, where several of the city's older temples sit close enough together to visit a handful without much backtracking, and use the rest of the day to get a feel for how spread out the rest of the city is before committing to a longer scooter trip.
Getting around
Walking covers the historic core reasonably well, but Tainan's food and temple destinations are spread across a wider area than a single walkable district, and public bus coverage is thinner than in Taipei. Many visitors rent a scooter for a day or two to cover more ground, which requires a valid license recognized in Taiwan — confirm the current licensing requirement for foreign visitors before you plan around this, since it depends on your home country's license and whether it's paired with an International Driving Permit.
Taxis are a reasonable fallback for shorter hops or when you'd rather not deal with scooter traffic, and ride-hailing apps operate in Taiwan the same way they do elsewhere, subject to local availability.
City buses connect the main train station area to some of the wider districts, but routes and frequency are less extensive than in Taipei, so build extra time into any plan that depends on a specific bus connection, especially if you're heading somewhere outside the historic core.
Language and everyday communication
English signage is more common around major tourist sites, transit hubs, and hotels than at small food stalls and neighborhood shops, which is typical of Taiwan generally but worth expecting in Tainan specifically since so much of the city's appeal is in exactly those smaller, less English-oriented places. A translation app on your phone makes ordering food and asking simple questions considerably easier, and most stall owners are used to gesturing or pointing at a menu with visitors who don't share a language.
Paying and staying connected
Cash is common at Tainan's smaller food stalls, traditional markets, and many independent shops, while cards and Taiwan's transit smartcards — EasyCard and iPASS — work at convenience stores, chain outlets, and public transit. Carry enough cash for a day of street food and market browsing rather than assuming a card will cover everything.
Taiwan uses Type A and Type B electrical plugs at 110V, so bring an adapter if your devices use a different plug shape, and check whether your electronics are rated for 110V if you're used to a different voltage at home.
What to confirm before you go
Opening hours for specific temples, museums, and historic sites vary and some close on particular weekdays, so check the current hours for anything you specifically want to see rather than assuming standard hours apply. Weather matters too — Tainan's summer heat and occasional heavy rain can change how much walking is comfortable in a day, so check the seasonal forecast pattern for your travel dates before finalizing an itinerary.
