Traditionally, the fastest and the most convenient way to get to Kazakhstan is an air-flight to Astana or Almaty. There are many international airlines operating flights to/from Almaty and Astana. You can travel to Kazakhstan by train from Russia; the road will take slightly more than 24 hrs. Also, you can get by car from neighboring countries: to Almaty and Chimkent you can drive from Uzbekistan, Kyrgyzstan and China, and to other cities in the north of the country including Astana, you can reach from different regions of Russia. Besides, in the western part of the country, on the shores of the Caspian Sea, Kazakhstan has two port-cities Aktau and Atyrau, where you can get via naval ways from Azerbaijan and Turkmenistan. Though, this is rather adventurous choice, as you will be traveling by merchant ship due to no passenger connection.
