People should always venture into the mountains! Visiting Cangyuan Tiankeng in autumn and winter is a must. This karst giant, known as "the footprints of extraterrestrial visitors," is truly breathtaking! The main pit is 184 meters in diameter and 235 meters deep, equivalent to an 80-story building. Standing on the eagle-shaped glass viewing platform and looking down, the steep rock walls envelop the primeval forest at the bottom, with rare plants like tree ferns and palm trees covering the bottom, making you feel like you've stepped into a Jurassic wonderland.
During the dry season, there are few tourists, and a thin mist often rises in the mountains, creating a truly immersive atmosphere with the swirling clouds at the pit's entrance. The mountain air is quite cool in the mornings and evenings, so be sure to bring a windproof jacket. Descending along the boardwalk to the bottom of the pit, the humidity is high, the temperature is even lower, and you can hear the babbling of an underground river, while the epiphytes on the rock walls are lush and verdant. After viewing the cliff paintings, visit the sinkhole. On one side are the epic cliff paintings left by the Wa people three thousand years ago, and on the other side are the earth wonders created by millions of years of crustal movement. The collision of humanity and nature here is an experience that you can't miss when visiting Cangyuan.
