One day
Start at the Registan in the morning light, then walk to the Gur-e-Amir for Timur's tomb and on to the huge Bibi-Khanym Mosque. Visit the Siyob bazaar for lunch and the famous bread, spend the afternoon at the Shah-i-Zinda avenue of tiled tombs, and return to the Registan for the evening light or the floodlit night.
