Regardless of the place you are traveling to, you should make sure that you are fully aware of the travel conditions to be expected in the places that you are traveling to and the same applies to Central Asia travel. Firstly, you need to understand that you are in a totally different part of the world where the standards will be very different from your country. This simply means that Central Asia tour or your Silk Road travel is going to be highly demanding and you need to be very open minded if you want to enjoy your trip. A closed minded traveler will be putting everything under the microscope and eventually make their trip very miserable.
If you are traveling in summer, you should be prepared to face a very tough summer; the temperatures can found to be too hot especially in the months between June and August.
