The Magura Cave, located in northeastern Bulgaria, is one of the country's largest and most beautiful caves in Bulgaria. It's in Rabisha, about 23 kilometers from Belogradchik, which has Bulgaria's most beautiful castle.

The cave is famous for the prehistoric wall murals that can be found in one of the halls. The prehistoric wall paintings of Magura are strikingly similar to those of the Grotta dei Cervi in Italy, which are regarded the most important works of art of the European Post-Paleolithic age for its remarkable expression and creative depth. They represent dancing women, hunting men, tools, stars, planets, and animals and are between 10,000 and 8,000 years old. Many prehistoric creatures' bones, including cave hyenas, cave bears, otters, and wolves, have been discovered here. The UNESCO Tentative List of World Heritage Sites includes the Magura Cave.

The staff of the Belogradchik municipality, to which the cave's management was passed by the Bulgarian Council of Ministers in 2012, conducts guided tours.

The Devil's Throat Cave is 17 kilometers from Devin in the Western Rhodopes. It's one of the caves that doesn't have dazzlingly beautiful rock formations. The prospect of going on a true adventure of discovery, taking part in a strange and awe-inspiring underground country, fascinates visitors. The cave's entrance resembles a devil's head, and a tremendous waterfall cascades down its throat, captivating imaginations and inspiring various legends since ancient times.

Orpheus descended this opening to the underground kingdom of Hades in search of his lost love Eurydice, according to the most common version. Without branching in either direction, the cave descends straight down. The Trigrad River's water cascades down the cave's "throat" from a height of 42 meters, making it the Balkan Peninsula's highest underground waterfall. The cavern into which the waterfall falls is known as The Hall of Thunder because of the cascade's muffled roar. It's massive – Bulgaria's second-largest cavern. The water disappears via a funnel around 400 meters from the entrance. This funnel is more than 150 meters deep, and the underground river exits the cave and runs out amid the mountain peaks through another cave after emerging from the funnel into a 60-meter-long cavern.

The fact that nothing carried into The Devil's Mouth Cave by the river returns is a startling reality. Many attempts have been made to follow wood and other materials through the cave, but they invariably vanish without a trace in the underground river, piquant interest and teasing the imagination. Experiments with dyes have revealed that it takes more than 112 hours for water to travel the short distance between two openings, prompting assumptions about the cave's huge subsurface stream system.

Late spring and summer are the greatest times to come to The Devil's Throat Cave, when the cave's entrance is surrounded by energizing vegetation and the Rhodopes are at their most attractive. From the beginning of May to the end of October, the local spelunkers' club conducts boat descents into the caves. The club supplies all the essential equipment, including boats, life jackets, and life rafts.

The Yagodina Cave is located near the Rhodope town of Yagodina in the Buynovo Gorge. It is one of Bulgaria's most well-known and frequented caverns. Its galleries stretch for 8,501 meters, making it Bulgaria's fourth-longest cave and the longest in the Rhodopes. The cave is kept at a constant temperature of 6 to 8 degrees throughout the year, with a humidity of more than 90%. (as do most caves).

The Yagodina Cave is a multi-leveled marble cave complex. The cave's lowest level has been constructed, but there are two more levels connected to it. Two artificial apertures serve as entrances and exits for the tourist path. The cave's natural outlet lies a kilometer further down the Buynovo River, where Neolithic (both Stone and Bronze Age) items have been uncovered. Earthenware dishes, labor utensils, and an earthenware oven are among the discoveries. According to studies, the skilled potters who resided in this area obtained clay from the cave. After being excavated and rebuilt, the cave mouth was made into a museum exhibit.

Aside from the regular tourist trail, Rhodope Tourist Association guides lead tours through the Yagodina Cave's untamed, unexplored galleries. These portions of the cave, which require specific equipment to explore, offer strange and enticing vistas that are concealed from most visitors. Excursions to the Yagodina Cave's lighted areas are extreme tourism that needs strength and stamina, but the stunning views are well worth the effort.

Snezhanka is one of the most beautiful caves in Bulgaria. It is also known as the Rhodopes' Pearl and is one of Bulgaria's 100 Tourist Sites.

Although the cave is modest, it is abundant in natural cave decorations such as stalactites, stalagmites, sinter lakes, and flow stones. The name comes from the strangely shaped snow-white deposits that took millions of years to create, such as the Dolphin, the Sarakatsan, the Statue of Liberty, the Dwarfs, the Parrot, and Snow White herself — a maiden-shaped stalagmite waiting for her prince to arrive. The cave has various lovely rooms, including the Udder Room, the Big Room, and the Music Room, which are all connected to the Cave-in, which is under a bridge.

The cave is well-developed and open to the public on a daily basis. Near the entrance, there is a tea café and a souvenir kiosk. Every hour, new groups of visitors are formed. Taking photos is not permitted within the cave. The cave is under camera surveillance 24 hours a day, 7 days a week.
