The ancient site of Sarazm is to be found about 15 kms west off Penjikent in north-western part of Tajikistan. Travelling from Dushanbe, it takes about 4-5 hours to reach Penjikent and let me tell you, even though you might think otherwise, that's one of the best roads to be found across the country. The site itself is well-marked, behind a small fence and the excavations are protected by a roof. Some basic information is provided, but not very much. Info booklet can be bought in the Rudaki museum in Penjikent. I really missed a local tour guide here who would give us some context of the culture and the excavation works, as, for example in Cattalhoyuk in Turkey. Some of the artifacts that have been excavated from the ancient Sarazm can also be found in the Rudaki museum, so I'd recommend visiting that first.
