Grotte de Comblain
In 1900, a dog accidentally fell into a hole in the earth, leading to the discovery of the Grotte de Comblain. The cave was opened to the public after the discovery of several more chambers. This cave, which is recognized as a subterranean chamber of scientific significance, may be found on the slopes of the Comblain-au-Pont town in the Liège province.
Grotte de Comblain is unique in that it has its own ecology, which provides the ideal environment for bats to hibernate. The location has been designated as a "underground cavity of scientific interest" as a result of this. Everything is in place to safeguard this special habitat.
A 75-minute guided tour here offers you a good overview of all the discoveries that have been discovered here over the last century. It is also home to a small museum, as well as a cafeteria and free parking.
