Kaohsiung

Yes, especially if you've already seen Taipei or are pairing it with Tainan and Kenting. Kaohsiung is calmer, cheaper and more spread out than Taipei, with a strong arts scene at Pier-2, a working harbor that gives the city its character, and easy MRT access to night markets, temples and Cijin Island. Three or four nights is a fair test.

Three to five nights covers the city comfortably. Two days is enough for Pier-2, the Dome of Light, Lotus Pond, Cijin, and one big night market. Adding a third and fourth day opens up Tainan, Fo Guang Shan or Meinong as day trips. A full week lets you reach Kenting and Xiaoliuqiu using Kaohsiung as a base.

Mid-November through early April is the sweet spot. Temperatures sit between 18°C and 26°C with low humidity and almost no rain. May to September is hot, humid and includes Taiwan's typhoon season — July and August in particular can wipe out outdoor plans. Lunar New Year (late January or February) is busy but festive.

Cheap by East Asian standards. Mid-range travelers spend around US$80–100 a day including a comfortable hotel, MRT travel and night-market eating. Budget travelers manage on US$40–50 a day using hostels. A meal at a night market is US$4–8, an MRT ride is around US$1, and even four-star hotels rarely top US$130 a night outside Lunar New Year.

Kaohsiung is known as Taiwan's largest port city, a hub of street art and converted-warehouse arts districts (Pier-2 Art Center), enormous night markets like Liuhe and Rueifong, the Dragon and Tiger Pagodas at Lotus Pond, the Dome of Light glass installation, and easy ferry access to Cijin Island. It's the laid-back, southern counterweight to Taipei.

Both, but bring more cash than you would in Taipei. Hotels, malls, chain restaurants and convenience stores take cards. Night markets, small eateries, traditional shops, temples and many ferries are cash-only. Carry NT$2,000–3,000 in small bills, and get an EasyCard or iPass on arrival for MRT, buses and YouBike. ATMs are everywhere.

The MRT Red Line is the easiest option — Kaohsiung Airport station is directly under the terminal, runs every 4–8 minutes, takes 15–25 minutes to downtown and costs NT$30–50 (about US$1–1.50). Taxis are 20–30 minutes and NT$250–400 (US$8–13). Most central hotels are walking distance from a Red Line stop.

Tainan (15 minutes by HSR) for temples and old-capital food; Fo Guang Shan Buddha Museum (45 minutes) for the giant bronze Buddha; Meinong (90 minutes) for Hakka villages and paper umbrellas; Tianliao Moon World for badlands hiking; and Kenting National Park or Xiaoliuqiu Island (2–3 hours) for beaches and snorkeling.

Yancheng for first-timers wanting walkable Pier-2 and the harbor; Xinxing for MRT access and Liuhe Night Market on the doorstep; Lingya for modern hotels and harbor views around the 85 Sky Tower; Zuoying if you'll HSR out to other cities; and Gushan for a quieter, leafier base near Monkey Mountain and sunset spots.

Very safe. Violent crime against tourists is rare, the MRT runs late, and walking alone after midnight is genuinely fine in central districts. Locals are friendly and English is workable in tourist zones. The one real hazard is traffic — scooters run red lights, and crosswalk priority is loose. Look both ways twice, even on green.

Taipei if it's your first Taiwan trip and you want the polished capital experience: better restaurants, more nightlife, denser sights. Kaohsiung if you've already done Taipei, want lower prices and slower pace, prefer harbor-and-warehouse aesthetics over high-rise buzz, or are pairing the trip with Tainan and Kenting. Many travelers do both via the HSR.

Tainan wins on food and history; Kaohsiung wins on transport, scale and harbor scenery. Tainan is Taiwan's old capital with denser temples, older streets, and arguably the country's best traditional food, but it has no MRT. Kaohsiung has the MRT, the airport, the arts district, and a working coastline. Many travelers base in Kaohsiung and day-trip to Tainan.

Most Western travelers don't. Citizens of the US, Canada, UK, EU countries, Australia, New Zealand, Japan, South Korea and Singapore can enter visa-free for up to 90 days. You need a passport valid 6+ months, a confirmed onward ticket and proof of accommodation. You must also submit the Taiwan Arrival Card (TWAC) online within three days before arrival.

Night-market staples and seafood. Don't miss papaya milk, salt-baked prawns, oyster omelets, tiger milk tea, Cijin Island grilled squid and seafood, eel noodles, stir-fried cuttlefish, douhua tofu pudding, and aiyu jelly drinks. Liuhe and Rueifong night markets are the best one-stop spots; Cijin's seafood strip is the after-ferry classic.

Less than in Taipei, but enough to get by in tourist areas. MRT signage and announcements are bilingual, younger hotel and restaurant staff usually speak workable English, and Google Translate's camera mode handles menus well. Older taxi drivers and night-market vendors often don't speak English, so save destination addresses in Chinese on your phone.

Tropical and warm year-round. Winter (December–February) is mild, dry and the most pleasant for sightseeing, with daytime highs around 24°C. Summer (June–August) is hot and humid with highs near 32°C and frequent rain. May–September is the rainy and typhoon season — short, intense downpours rather than constant drizzle.
