The Trigrad Gorge represents a magnificent 7-kilometre gorge which for millions of years the Trigrad river has carved in the marble rocks north of the Rhodope village of Trigrad.
In places, the distance between the two slopes is 300 m, but in the real part of the gorge, which is 2-3 km long, they are only 100 m apart. On the west side, the height of the vertical rocks is 180 m, and from the east, they reach 300-350 m. These huge sizes make it third in size in Bulgaria. Near the river, somewhere cut in the rocks, passes the road to Trigrad – the characteristic mountainous one-lane road with counter-traffic. Passing on it requires a lot of attention and tolerance because two cars cannot move at the same time, but they are waiting for the numerous turns. The bustling road along the river and the tall rocks overhanging the two sides create the impression that Trigrad is a remote and inaccessible place, and the rocks are like fortress walls that keep the secrets of the mountain. The view of the huge vertical slopes, which are very close to each other on the upper part, and the scarce sunlight acts respectfully and the beautiful Rhodope nature complements the picture.
The Trigrad River disappears under the ground at the entrance to the Devil’s Throat cave to appear 530 meters further down from another cave. The Devil’s Throat is accessible to tourists and is one of the most impressive caves for the huge waterfall that forms the waters of the river – 42 m tall. There are many more caves in the area, most of which are very small (only 12 are more than 100 meters long). Very interesting and also accessible for tourists is the Harami cave, which is located in a rock wreath against the Devil’s Throat. In it are found remains of Neolithic homes and today models of people who lived there. Access to it is only possible with special equipment and a guide. Not far away is the beautiful Yagodinska cave.
