In Guangxi province, China, massive sinkholes, known as “tiankeng” or “heavenly pits,” have become a unique tourist attraction.
These giant pits, some over 100 meters deep, contain ancient, untouched ecosystems with rare plants and animals that have survived since prehistoric times.
The discovery of these ecosystems, including new species, has sparked both scientific interest and tourism.
While tourism boosts the local economy, concerns about the impact on these fragile environments are growing.
Experts stress the need for careful management to balance exploration with conservation.
Tourists, such as Rui and Michael, descend into these sinkholes with the help of expert guides, experiencing the thrill of exploring these hidden worlds.
However, some sinkholes have been closed to tourists to protect unique species, like rare orchids. Researchers urge responsible tourism practices, including aerial photography and remote viewing, to ensure these ecosystems are preserved for future generations.
