The Baatara gorge sinkhole (Baatara gorge waterfall) is a waterfall in the Chatine, Lebanon. Uncovered in 1952 in the town of Tannourine El-Fawqa by French bio-speleologist Henri Coiffait (1907-1989), it drops at an altitude of 255 meters inside a cave that forms a popular destination for tourists and adventure lovers.
The waterfall drops 255 meters into the Balaa Pothole, a cave of Jurassic limestone located on the Lebanon Mountain Trail. The cave is also known as the Cave of the Three Bridges. Traveling from Laklouk to Tannourine one passes the village of Balaa, and the Three Bridges Chasm (in French Gouffre des Trois Ponts) is a five-minute journey into the valley below where one sees three natural bridges, rising one above the other and overhanging a chasm descending into Mount Lebanon. During the spring melt, a 90–100-meter cascade falls behind the three bridges and then down into the 240-meter chasm.
Some stories of explorers of the waterfall estimate that it is 160 million years old, which means, if true, that it would be the oldest waterfall in the world.
