By far the best exhibit we have visited in China so far. It's easy to get to by private bus from Xi'an, the 603 to the train station and then the 306 to the Tomb, then repeat in reverse. There is no need to take a tour and all you will be doing is adding 100-200 Yuan to the cost of your day for a few facts from a tour guide and a meal you probably don't need. Excellent English signed and make sure that you take heed of the Lonely Planet and do the exhibition, pit 3 pit 2 and then pit one, it's by far the best order to see the exhibition.
