We recently spent 4 days in the Zhangjiajie area and had organised a guide prior through recommendations on TA.
We chose Jeffrey Tang and are so glad we did. Jeffrey and his driver met our late flight at 10.30pm and took us to our hotel. The next 2 days we spent with Jeffrey's guide Grace site seeing around the area.
Jeffrey went out of his way to make sure that we were OK. He is very professional and a charming person. We enjoyed our time with Grace and feel that we got to see more of the park with her help in the limited time that we had. She was a delight to be with and we will always remember her singing songs to us from the Fox Fairy show on the cable car.
We highly recommend Jeffrey and Grace if you are considering a guide for your visit to Zhangjiajie.
