Can I leave the airport on a layover in Taipei?

Taoyuan Airport (TPE) sits about 40 km west of downtown, connected by the MRT Express that drops you at Taipei Main Station for 160 TWD, roughly $5 at current rates. Immigration tends to move quickly, often under 20 minutes with the automated e-gate lanes available to many nationalities. Budget 90 minutes for the return through security and boarding. That arithmetic puts the honest floor at six hours. Under that, stay airside. TPE's Terminal 1 food court has a solid beef noodle soup stall with bowls for 180-250 TWD, the broth hot enough to fog your glasses in the terminal air conditioning. With eight hours, you can loop through Ximending and Liberty Square with a proper meal between them.

The smartest layover route stays near the MRT Blue and Red lines radiating from Taipei Main. Walk 10 minutes south to Liberty Square, where Chiang Kai-shek Memorial Hall (opened 1980) stands at the far end of a white-tiled plaza that throws the August heat right back at you, 33°C in the shade and closer to 37 with the humidity. The hourly changing of the guard, all synchronized boot-stamps on marble, runs until 17:00. From there, ride one stop west on the Blue line to Ximen for Ximending, Taipei's main pedestrian quarter. The narrow lanes smell like grilled pepper buns and sesame oil. Solo travelers do well here because every stall serves one person without question, no reservation needed. Shaved mango ice from the shops along Emei Street runs 120-180 TWD, and most street food costs 50-100 TWD per item. For evening layovers, Shilin Night Market opens around 17:00, about 15 minutes further north on the Red line. Vendors call out orders over the sizzle of chicken cutlets, and solo diners have the advantage since every stall is built for parties of one.

Taipei scores 8.5/10 on TTDI's solo-traveler safety index (see the TTDI Solo-Safety Index), and it earns that number. The MRT runs until midnight, every station staffed and well-lit, with designated women's waiting zones marked by pink floor strips on the platform. I'd walk Da'an, Zhongzheng, and Ximending alone after dark without thinking twice. The one street that gets a caveat is Linsen North Road between Zhongshan and Nanjing Fuxing MRT stations, Taipei's hostess-bar strip. Not dangerous, but solo women will encounter persistent touts after about 21:00. Cross to a parallel street and the hassle stops. For meeting people on a short stay, the hostel common rooms near North Gate fill up by evening. Star Hostel, a 5-minute walk from Taipei Main, has a rooftop lounge overlooking the old North Gate, private rooms from about 1,400 TWD, and the kind of communal kitchen where travelers end up swapping routes over convenience-store beer. If your layover falls during daylight, the cafes along Yongkang Street in Da'an draw remote workers and language-exchange groups most afternoons.

Buy an EasyCard at any MRT station 7-Eleven for a 100 TWD deposit and load 200-300 TWD for a layover's worth of transit. It works on trains, buses, and at most convenience stores. ATMs accepting foreign cards sit inside every FamilyMart and 7-Eleven, roughly one every 200 meters in the central districts. Cash still rules at night markets and smaller stalls. For the return, board the Airport MRT from Taipei Main no later than three hours before your departure. The last express train leaves at 23:35. Miss it and a taxi to TPE runs 1,000-1,200 TWD, about 40-50 minutes on the freeway depending on traffic. Mind you, TPE's departure hall has a long corridor between immigration and the gates. That walk alone can take 10-15 minutes, so factor it into your buffer.
