Recently discovered in the China’s Chongquing province, the Er Wang Dong Cave is so large–the cave’s passages run 138,251 ft–it has its own weather system. The cave was discovered by a team of 15 cavers and photographers.

Upon entering the cave, the team found themselves inside what is now named “Cloud Ladder Hall.” This space measures 12 1/2 acres and has a ceiling 820 feet tall–a space so large it’s been known to have its own cloud.
