Jiufen Old Street in February

Come on weekdays if possible — weekends bring tour bus chaos that can make the narrow streets nearly impassable. The sweet spot is arriving around 3 PM, exploring before the crowds hit, then staying for the lantern lighting at dusk. Jiufen gets rain about 200 days a year, so pack an umbrella regardless of the forecast. The mist actually adds to the atmosphere, but heavy rain makes the steep stone steps treacherous. Spring and fall offer the clearest mountain views, while winter brings dramatic fog that makes everything look extra mystical. Summer gets humid and packed with tourists. Wear comfortable walking shoes — these streets are steep and slippery when wet. Most shops close by 8 PM, but a few teahouses stay open later. The famous taro balls sell out by evening, so try them early. And here's a local tip: the public restrooms are scarce and often have long lines, so use facilities in restaurants when you can.
