西安半日遊：4小時精華路線
只有一個下午？出差途中擠出了幾小時？或者轉機時間夠長、想逃離機場？這條壓縮路線帶你看到離開西安前必看的三樣東西——而且晚上7點前就回到飯店了。
鐘樓 → 回民街 → 城牆看日落。 三個點、四個小時，全程在老城牆內步行。你會吃到城裡最好的街頭小吃，看到明代的鐘樓，最後在點燈的600年老城牆上收尾。預算約人民幣 70–120 元（主要是吃＋一張門票）；不排博物館、不坐車去兵馬俑（那個留給完整的一天）。
穿好走的鞋，帶上支付寶或微信支付——坊上基本不用現金。
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.
