西安半日游：4小时精华路线
只有一个下午？出差途中挤出了几小时？或者转机时间够长、想逃离机场？这条压缩路线带你看到离开西安前必须看的三样东西——而且晚上7点前就回到酒店了。
钟楼 → 回民街 → 城墙看日落。 三个点、四个小时，全程在老城墙内步行。你会吃到城里最好的街头小吃，看到明代的钟楼，最后在点灯的600年老城墙上收尾。预算约¥70–120（主要是吃+一张门票）；不排博物馆、不坐车去兵马俑（那个留给完整的一天）。
穿舒适的鞋，带上支付宝或微信支付——坊上基本不用现金。
第 1 天
Start at the Bell Tower (钟楼, Zhōnglóu) — the geographic and symbolic center of Xi'an, where the four main streets of the old city meet under a Ming-dynasty wooden tower. You don't need to climb it (¥30, 30 min if you do); the photos from the pedestrian underpass are the shot everyone takes, and they're free. This is your orientation point — everything on this half-day walk radiates from here.
Walk 10 minutes north into the Muslim Quarter — follow the crowd.
The Muslim Quarter (回民街 / 回坊, Huífāng) is Xi'an's food soul and the single best use of two hours in the city. Skip the souvenir-choked main strip (Beiyuanmen) after the first 50 meters and duck into the side lanes — Dapiyuan (大皮院) and the alleys behind — where the real eating happens. Grab a roujiamo (肉夹馍, the Xi'an pork "burger"), a bowl of biang biang noodles, and a persimmon cake from a street cart; ¥30–50 buys a feast. If you have time, peek into the Great Mosque (清真大寺, ¥25, Chinese-temple courtyards unlike any mosque you've seen).
Walk 15 minutes south to the South Gate of the City Wall (Yongningmen).
End on the City Wall (城墙, Chéngqiáng) at golden hour — enter at the South Gate (永宁门, Yǒngníngmén), climb the ramparts, and watch the old city light up as the sun drops behind the rooftops. ¥54 admission; you can rent a bike (¥45/3h) and ride a stretch of the 13.7 km circuit, or just walk the ramparts for 30 minutes and take in the view. The wall stays open until 22:00 in season, so there's no rush — this is the moment the day clicks into place. Metro Line 2 (Yongningmen station) takes you home from the gate.
Done — metro, taxi, or walk back to your hotel.
