The Heavenly Well, also known as Xiaozhai Tiankeng, is a natural wonder located in Fengjie County, Chongqing Municipality, China. It is the deepest sink in the world, measuring over 662 meters (2,172 feet) deep and 626 meters (2,054 feet) wide, with a total area of approximately 119,000 square meters (29 acres). The Heavenly Well is a popular tourist destination, attracting visitors from all over the world who come to marvel at its incredible size and beauty.

The sink was formed over millions of years by the erosion of the local limestone bedrock. Water flowed through the cracks and crevices in the rock, gradually widening them and creating the vast open space that we see today. The Heavenly Well is surrounded by towering cliffs and dense forests, which add to its sense of grandeur and mystery.

The name “Heavenly Well” comes from the belief that the sink is a gateway to the underworld. According to Chinese mythology, it is one of the nine pits of hell, and the spirits of the dead pass through it on their journey to the afterlife. Despite this eerie reputation, the Heavenly Well is also considered a sacred place by the local Miao people, who believe that it is home to the gods and spirits of the natural world.

Visitors to the Heavenly Well can explore the area on foot, following a series of well-maintained trails and boardwalks that wind their way around the sink. There are also several viewing platforms that offer breathtaking panoramic views of the sink and the surrounding landscape. For the more adventurous, there are opportunities for hiking, rock climbing, and even bungee jumping from the cliffs above the sink.

The Heavenly Well is a unique and awe-inspiring natural wonder that showcases the power and beauty of the natural world. Its incredible size and mysterious reputation make it a must-see destination for anyone visiting China, and a true bucket-list item for adventurous travelers.
