Yagodinska Cave (Bulgarian : Ягодинска пещера) is a cave in the Rhodope Mountains, southern Bulgaria. It is included in the 100 Tourist Sites of Bulgaria under № 89. It is named after the homonymous village nearby. With a total length of 10,500 m, Yagodinska is the third longest cave in the country after Duhlata and Orlova Chuka and the longest in the Rhodopes. Yagodinska Cave is home to 11 species of bats.
Yagodinska Cave is on the right bank of the river Buynovska, a tributary to the Vacha, on the slopes of the Buynovo gorge — the longest gorge in Bulgaria. It is in Smolyan Province at 20 km to the south of the town of Devin and 3 km to south-west of the village of Yagodina. The cave is accessible through the road Devin–Dospat and has a parking lot. The cave entrance is at an altitude of 930 m.
The exploration of the cave commenced in 1963 by the Speleological Club of Chepelare led by Dimitar Raychev. Initially 8,500 m have been explored and 2,000 m more galleries were discovered during the second mapping of the cave in 1982-1986. The age of the cave is estimated at 275,000 years.
Yagodinska Cave is 10,500 m long and has three levels, of which only a 1,100 m path in the lowest level was electrified in 1971–1982 and opened for tourists. The entrance and the exit for that level are artificial tunnels with a length of 150 and 80 m respectively. The altitude of the entrance and the exit is 930 m and 937 m respectively. The temperature in the show cave is constant all year round at 6ºС; the humidity is 85%–91%.
Yagodinska contains a very large number of cave formations, or speleothems, including stalactites, stalagmites, stalagnates, flowstone, draperies and cave pearls.
The natural entrance leads to the uppermost level, where an ancient dwelling dated to the 4th millennium BC was discovered. Excavations have proven that the dwelling was an important centre producing ceramics. The clay was extracted from the interior of the cave and from the bed of the Boynovska River. The pottery was baked in clay furnaces. The inhabitants abandoned the site as a result of a collapse caused by an earthquake.
Yagodinska Cave is an important site for bats due to the large length of its galleries. The cave is home to 11 species of bats. Of these, six species are of conservation importance in Europe: the greater and the lesser horseshoe bats, the greater and lesser mouse-eared bats, Bechstein's bat and Geoffroy's bat.

The Petralona cave also Cave of the Red Stones, a karst formation, is located at 300 m (984 ft) above sea-level on the western foot of Mount Katsika, about 1 km (0.62 mi) east of the village of Petralona, about 35 km (22 mi) south-east of Thessaloniki city on the Chalkidiki peninsula, Greece. The site came to public attention when in 1960 a fossilized archaic human skull was found. The cave had been discovered accidentally only a year earlier (1959) after erosion had left clefts in the rock. "Bejeweled" with impressive stalactite and stalagmite formations and holding an abundance of fossils, the cave soon attracted geologists and paleontologists. After decades of excavations the cave is open to the public and scientific work is documented and presented in an adjacent archaeological museum.

Orlova Chuka is a cave situated in the Danubian Plain, north-eastern Bulgaria. With a total length of 13,437 m, Orlova Chuka is the second longest cave in the country after Duhlata. The cave was discovered in 1941 and opened for tourists in 1957. Orlova Chuka is home to 14 species of bats.
A maternity colony refers to a temporary association of reproductive female bats for giving birth to, nursing, and weaning their pups. The colonies are initiated by pregnant bats. After giving birth, the colony consists of the lactating females and their offspring. After weaning, juveniles will leave the maternity colony, and the colony itself will break apart. The size of a maternity colony is highly variable by species, with some species forming colonies consisting of ten or fewer individuals, while the largest maternity colony in the world in Bracken Cave is estimated to have over 15 million bats.
