On your final day, visit the nearby Zhangjiajie National Forest Park, which served as inspiration for the movie 'Avatar.' Start by taking a shuttle bus to the park entrance and then explore the various scenic spots within the park. Marvel at the towering sandstone pillars, lush forests, and serene streams. Don't miss the famous 'Hallelujah Mountain,' which resembles the floating mountains depicted in the movie. Take a leisurely walk along the Golden Whip Stream, a picturesque trail that offers stunning views of the surrounding nature. If time permits, you can also visit the Yuanjiajie Scenic Area, known for its breathtaking views and unique rock formations. After a day of exploration, head back to Zhangjiajie City and prepare for your departure.
