Samarkand through Bukhara
Samarkand through Bukhara is the most visited and most famous region of the historic Silk Road through Central Asia. It is comprised of the Uzbekistani provinces of Samarkand and Bukhara, naturally, as well as the southern portion of Navoiy Province.
Tajik is the main language since the a large Tajik minority lives in Samarqand and Bukhara regions. Uzbek and Russian are the second languages.
However, there are no signs in Tajik and few signs in Russian. Most are in Uzbek.
