Kashgar is an ancient city, and in walking the streets of its Old Town, you can still get a sense of what this legendary Central Asian hub was like in the days of the Silk Road. 500-year old remnants of the city wall, narrow lanes and colorful multi-ethnic crowds combine to make Kashgar's historic district a highlight of any visit to the city. Modernity is, of course, changing the face of the city and much of Old Town has suffered the consequences, whether it be in the form of character-draining makeovers of old adobe houses or the imposition of an RMB 10 entry fee to visit the far eastern section of Old Town, but the wild and ragged spirit of the place persists despite efforts to sanitize and regulate. Give yourself an hour or two to simply wander and explore and you'll be rewarded.
