Individuals travel from Changsha to Zhangjiajie and fenghuang

Hey, I know Travel China Guide provides such independent travels. They would help you book train or flight tickets as well as hotels and pick you up in the airport or train station. But for the travel, you can make it on your own. They provide very considerate service and the price is reasonable. If u are interested, here is their email for your convenience:
