One Week In one week you can cover 'the big three' in a trans-steppe dash. Start in impressive Samarkand to explore the pearls of Timurid-era architecture, zip to enchanting Bukhara to see the Lyabi-Hauz, tour the Ark and gape at the 47m Kalon Minaret and its stunning mosque, before continuing to perfectly preserved Khiva. Fly back from Urgench.
Two Weeks In two weeks you can do the five major places of interest in Uzbekistan at an unhurried pace. Fly west to Nukus and spend a half-day appreciating Central Asia’s greatest art collection before heading to Khiva via the ancient ruined fortresses of Elliq-Qala. Spend a few days in both Bukhara and Samarkand before ending up in Tashkent for some museum hopping, good food and a night or two on the town.
One Month All of the above sights can be seen in a month at a more relaxed pace. You can also visit both Termiz and the Fergana Valley and devote more time to exploring Uzbekistan’s natural wonders, including hiking in the Chimgan region and homestay tourism in the Nuratau Mountains.
