To reach the Dujiangyan Irrigation System from Chengdu, the most efficient method is taking a high-speed train, which takes approximately 20 to 45 minutes and costs between 10 and 27 CNY. While some services depart from Chengdu East or South stations, most trains leave from Xipu Railway Station, which is easily accessible from the city center via Metro Line 2 or Line 6. For the closest access to the scenic area, travelers should book tickets to Lidui Park Station, which is just a 10-to-15-minute walk or a short bus ride (routes 4, 5, 7, or 17) from the entrance. If you arrive at the main Dujiangyan Railway Station, you will need to take a 40-to-50-minute bus ride or a 10-minute taxi to reach the site. Alternatively, direct tourist shuttle buses depart from major city landmarks like Chunxi Road, the Wide and Narrow Alleys, and the Chengdu Panda Base, typically taking around 2.5 hours for a fare of approximately 58 CNY. For those preferring private transport, a taxi or Didi ride-share from downtown Chengdu takes about 45 minutes to 1.5 hours and costs roughly 100 to 160 CNY. Regardless of the method chosen, it is highly recommended to book train tickets in advance, especially during weekends and holidays, as they sell out quickly.
