Xi'an's city wall is 14 km long, 12m high, and 12-18m wide — built 1370 under the Ming dynasty atop the original Tang foundations. Four main gates (South/Yongning, North/Anyuan, East/Changle, West/Anding). Entry 54 RMB. Rent a bike at South Gate (45 RMB / 100-min single, 100 RMB / 3-hour electric scooter) — the entire wall ride is 12-14 km / 90 min. Pedestrian only at the corner watchtowers. Best at sunset for golden hour + lantern lights coming on (the wall is uplit nightly). Combine the South Gate entry with Bell Tower (5 min walk north) — both connect via the wide pedestrian boulevard.

What Chinese travelers actually do here

Distilled from Chinese-language travel notes — the practical tips most English guides miss.

▸Bike the wall, don't walk it. The 13.7 km loop on foot takes 4+ hours and is exhausting — the rental bike at South Gate (¥45 for 100 min) does the full loop in 75 minutes with stops. Most foreigners walk a short stretch and miss the western+northern walls which have the best old-city views.
▸Tickets are valid 2 days — you can leave and re-enter, useful for splitting the visit into a daytime bike loop + evening lantern walk. Show your ticket QR code at any gate.
▸Best photo angle is NOT the famous South Gate (everyone goes there). The NORTHEAST CORNER (大北角) at sunset has the wall + watchtower silhouette + Muslim Quarter rooftops in one frame. Walk or bike there 30 min before sundown.
▸Lantern Festival (mid-February to early March) lights the entire wall with red lanterns — this is the most photogenic time of year but also the most crowded. Off-season (October-November or April) has the lanterns hung year-round at lower density and 1/5 the crowds.
▸Muslim Quarter (回民街) is 5 minutes from the South Gate after exiting — pair the wall bike loop with a Muslim Quarter dinner at 6-8 PM. Specific stalls: paomo (羊肉泡馍) at Lao Sun Jia (老孙家), rou jia mo (肉夹馍) at Lao Liu Jia (老刘家), and persimmon cakes at the stalls near the central mosque.
▸Don't bother with the 'Tang Dynasty Costume Rental' photo packages (¥150-300) advertised at the South Gate — the costumes are polyester knockoffs and the rental shops charge for photos as a separate fee. If you actually want this experience, do it at the Daming Palace ruins or Huaqing Pool instead with better costumes for the same price.
▸If staying within the walled city, choose a hotel near North Avenue (北大街) or West Avenue (西大街) — the South Gate area is touristy and noisy at night. The hotel SOFITEL Renmin Square is a Soviet-era restored property with the best wall view from rooms.
