The most efficient and popular way to travel from Chengdu to Chongqing is by high-speed train, which typically takes between 1 and 2.5 hours depending on the specific service. With over 100 daily departures primarily from Chengdu East Railway Station, these trains offer high flexibility and arrive at various stations in Chongqing, such as Chongqing North, Chongqing West, or Shapingba. Tickets for a second-class seat generally range from 96.5 to 161 CNY. For budget-conscious travelers, normal-speed trains are also available, taking 3 to 5 hours for approximately 46.5 to 50.5 CNY. Alternatively, long-distance buses depart from stations like Chadianzi or Chengdu East, taking about 3.5 to 4 hours with fares starting around 88 CNY. While driving or taking a taxi is an option and takes roughly 3 to 4 hours, it is generally more expensive and less convenient than the high-speed rail network.
