Hong Kong has been a gateway between the east and west for decades. Located on the coast of southern China, Hong Kong is easily accessible from Xi'an by plane or train. 

A tourist visa may be required to travel from China to Hong Kong, which has separate immigration and customs procedures from China. Depending on your country of citizenship and your itinerary, you may be eligible to travel in Hong Kong visa-free for seven to 180 days.

Once in Hong Kong, it's best to hire a driver so you can ride comfortably and go at your own pace, but more adventurous travelers may find Hong Kong's bustling subway and ferry system very efficient for moving about Hong Kong.

There are plenty of itineraries to inspire your travels, like this 12-day Beijing to Hong Kong Grand Tour which includes two nights in Xi'an.

By Plane

Duration: 3.5 hours

The most direct and convenient way to get from Xi'an to Hong Kong is to fly. The 888-mile (1,430 km) journey takes three hours and 25 minutes.

There are only a couple of daily nonstop flights from Xi'an Xianyang International Airport to Hong Kong International Airport although some intrepid travelers consider flying from Xi'an Xianyang International Airport to Shenzhen Boa'an International Airport⁠—as there are more than a dozen daily nonstop flights⁠—and then traveling from Shenzhen to Hong Kong.

The flight time from Xi'an to Shenzhen is two hours and 45 minutes, but the time it takes to travel from Shenzhen to Hong Kong can take an hour or more by private car transfer.

By Train

Duration: 9.5-12 hours 

More than RMB220 billion was spent to build China's high-speed rail system (gāotiě)—the largest in the world—which makes it an enticing, but slower, option.

There isn't direct, nonstop train service from Xi'an to Hong Kong. Rather, travelers must take a high-speed train from Xi'an North Railway Station to Guangzhou South Railway Station or Shenzhen North Railway Station and then transfer to a high-speed train to Hong Kong West Kowloon Station.

Most trains have a food serving counter or dining car with simple fare like xīhóngshì chǎo jīdàn (scrambled eggs with tomatoes) and there are hot water dispensers to use for making instant noodles, coffee, and tea. Once passengers arrive in Hong Kong, they clear customs and immigration for both China and Hong Kong from within the train station.
