“Yagodina” Cave is located in the Buynovo Gorge near the Rhodope village of Yagodina. It is one of the most famous and most visited caves in Bulgaria. Its galleries extend to a length of 8,501 meters, which makes it the 4th longest cave in Bulgaria and the longest in the Rhodopes. The temperature in the cave is between 6 and 8 degrees C all year round, and it has a humidity of more than 90% (as do most caves).
The itinerary continues for another kilometer, affording visitors the opportunity to observe almost every type of cave formation, but most impressive are the cave pearls. They are formed the way real pearls do, beginning with grains of sand that fall into the water and then are coated with layer after layer of calcite, year after year, and that is way they have a round shapre.
