Shanghai from Suzhou or Nanjing

Shanghai, China's largest city, is an easy day trip from the Jiangsu rail corridor by high-speed train. From Suzhou the ride to Shanghai Hongqiao takes 25 to 35 minutes (CNY 35-45), and from Nanjing South it takes 1 to 1.5 hours (CNY 134-145); Wuxi is in between. Suzhou lies about 100 km west of the city. From Hongqiao, Metro Lines 2 and 10 reach the centre in 30 to 40 minutes for CNY 4-7, and the metro is faster and cheaper than taxis in central districts. The Bund, a waterfront promenade of early twentieth-century banking buildings, faces the Pudong skyline across the Huangpu River, with the Oriental Pearl Tower and other towers dominating the view. Yu Garden and the surrounding Old City bazaar preserve a Ming-dynasty garden (about CNY 40) with rockeries, pavilions and a busy market area. The former French Concession offers tree-lined streets, cafes, boutiques and colonial-era houses, best explored on foot. A one-day arc starts with an early train, reaching Hongqiao by 8:30, then Yu Garden and the Old City before crowds build. Lunch can be soup dumplings (xiaolongbao) or other Shanghai dishes in the Old City or the French Concession. The afternoon fits a walk through the French Concession, then the Bund at dusk, when the skyline lights come on, and optionally a Pudong viewpoint. The last return trains to Suzhou and Nanjing depart late in the evening, but return seats should be booked in advance, especially at weekends and holidays. The best seasons are March to May and September to November; summer is hot and humid, and winter is cold and damp. A passport is required for train tickets and some sights. With up to twelve hours of walking and metro transfers, the day is rated moderate.
