Taipei resists summary. It is a 24-hour bookshop, a shouting night market, incense at a 270-year-old temple and a youth-culture quarter all inside the same metro map. Every MRT exit hands you a different city: step off at Ximen for the pedestrian neon of Ximending, at Longshan Temple for the oldest market streets in the basin, at Xinbeitou for streets that steam with hot-spring water, at Tamsui for a river sunset.
What surprises first-timers is the gentleness. Passengers queue to the right on escalators and leave the priority seats empty even in a crush; strangers walk you to your destination rather than pointing. The old line about Taiwan is that the finest scenery is the people, and Taipei is where that line was invented.
The city is also built for eating. Every neighbourhood keeps its own night market — Shilin for the greatest hits, Ningxia for a 200-metre strip of old-school stalls, Raohe for pepper buns, Huaxi for the old snake alley — and the side streets hide beef-noodle shops that sell out by noon. A meal of small dishes runs NT$150–250 and is the best money you will spend.
It is the easiest base on the island. The high-speed rail runs from Taipei Main Station to Kaohsiung's Zuoying in about 2 hours, the conventional rail and the Pingxi branch line reach the old mining towns in under an hour, and Jiufen's lantern-lit stairways are a day trip. Four days is the honest minimum; five lets you keep a slow day in Tamsui or Maokong.
