To travel from the Zigong Dinosaur Museum back to Chengdu, the most efficient method is to take a taxi or public Bus 35 for approximately 10 kilometers to the Zigong Bus Station or Zigong Railway Station. From Zigong Railway Station, high-speed trains are the fastest option, reaching Chengdu East Railway Station in about 1 to 1.5 hours, with tickets typically costing between 80 and 160 CNY. Alternatively, frequent long-distance buses depart from the Zigong Bus Terminal to various stations in Chengdu, such as Xinnanmen or the North Gate Bus Station, a journey that takes approximately 3 hours and costs around 80 to 120 CNY. For those preferring a direct door-to-door service, a taxi or ride-hailing app like Didi can make the 180-kilometer trip in roughly 2 hours, with fares ranging from 380 to 480 CNY.
