On the first day of your trip to Mount Tianmen, start by arriving at Zhangjiajie City. From there, make your way to the famous Tianmen Mountain. Begin your adventure by taking the Tianmen Mountain Cableway, which is one of the longest cableways in the world. As you ascend, marvel at the breathtaking views of the surrounding landscapes, including lush forests and towering cliffs. Once you reach the mountaintop, explore the Tianmen Cave, also known as the Gateway to Heaven. This natural archway offers stunning views and is a popular spot for photography. Afterward, take a leisurely walk along the Cliff-Hanging Walkway, a glass skywalk that offers a thrilling experience. End your day by watching the sunset from the mountaintop and then head back to your accommodation in Zhangjiajie City.
