The Cave Of Three Bridges
The Baatara gorge waterfall (also known as the “Cave of the Three Bridges”) in Tannourine, Lebanon. The waterfall drops 255 metres (837 ft) into the Baatara Pothole, a cave of Jurassic limestone located on the Lebanon Mountain Trail.
Highest suspension bridge in the world. Dizzying height. As I walked accross I thought, "If I fell from this height, I would have time to write a suicide note, and poison myself before I hit the bottom." Royal Gorge, Colorado
