You can fly to Hohhot or Baotou. There is only one train to Ejina every day. It starts from Hohhot at about five o&;clock in the afternoon and stops at Baotou. It takes almost 13 hours. The next morning, you can start your journey directly. It&;s ok to sign up for a local tour group ~ After all, the scenic spots are far away, and you have to take a bus.
