The Chudnite Mostove (Wonderful Bridges) are two natural bridges, which are the remains of the same cave system. Both are located along the Aidarsko Dere River, under a mountain ridge called Chernatitsa. Although someone spread the story about an earthquake, the tale is mentioned on numerous webpages, the formation of natural bridges is just the normal development of karst. After the cavs hae grown to some size, they eventually reach the surface, parts of the ceiling are eroded and the caves become roofless. The newest theories about roofless caves even deny roof collapses completely. However, much of the valley around the bridges is simply former cave.
The rock is composed of marble, not normal limestone. The bigger bridge is 96m long with an impressive entrance 45m high and 43m wide. The smaller bridge is located 200m down the valley and is only 60m long.
During the last years the bridges have become a popular tourist destination. There are trails to and through the bridges. There is also a tourist lodge named Chudnite Mostove close to the upper bridge. The place is reached on a third-class road branching off the Assenovgrad-Smolyan road to Zaburdo.
