High-speed train tickets from Chengdu to Emei/Leshan can be purchased via the 12306 official website/app or third-party platforms like Ctrip. Foreigners must register with a passport and complete real-name verification. Book online in advance to avoid queues, especially during holidays when tickets are tight. Passport details are required for booking, and the original passport must be used at manual channels for boarding—electronic tickets can’t be scanned directly with a passport. Chengdu East Railway Station has a Foreign Passenger Service Station to assist with bookings and changes. Feel free to contact service@intotravelchina.com for ticket booking and itinerary planning—we’ll handle the details for you.
