Today, you'll travel to Xi'an by high-speed train. The capital of the Shaanxi province, Xi’an is the largest city in northwest China. Once the imperial centre of China for 13 dynasties, modern Xi'an is dotted with historic sites ripe for exploring. Join your leader on a short walking tour to uncover what was the start of the ancient trading route, the Silk Road. In the city’s Muslim Quarter, you’ll wander through the narrow streets, passing shops, lively markets and endless stalls of street food. For the rest of the day, maybe visit the City Wall, which extends more than 13 km (8 mi) around the city – cycling is a great way to explore it. Or, visit the Bell and Drum Towers – according to legend, the former was built to restrain the dragons that were causing earthquakes. The latter is (unsurprisingly) full of drums that were once used to mark time and warn of emergencies. Xi’an’s history as a major hub on the Silk Road means it has an exciting mixture of cultures – this is exemplified by its food options. This evening, perhaps visit the night markets and try the tantalising local specialties such as pao mo (lamb broth that you break flatbread into), hand-pulled noodles, hot pot and grilled skewers.
