When is subway line 3-6 are ready to use in Xian? how to go from airport to forest city hotel?

Well, as far as I know, subway line 3 will be operated in the end of 2015. And the subway line 6 will be operated in 2018.

To the hotel, you need to take airport shuttle bus line 3 and get off at Railway Station first. The bus fare is CNY26 per person. Then take a taxi to the hotel directly at the cost of CNY9-10.

The nearest metro station from your hotel is Zhonglou (Bell Tower) Station. And the distance between your hotel and the muslim quarter is about 1.7 miles. You can walk to there in around 15min. In this way, you can enjoy the beautiful scenery of Bell Tower and the surroundings
