"Eleninа Dupka" (Elenina Hole) Cave (peshterata Elenina Dupka, пещерата Еленина дупка) near the village of Byala Voda, Malko Tarnovo Municipality, Burgas District.
There is a legend that says that when the girls from Byala Voda were dancing, a strong whirlwind appeared and picked up one of them, named Elena. After a while, they found her braids at the entrance to the cave, which meant that the girl had been abducted by a dragon that lived there.
The cave is located west of the village of Byala Voda, 47 km from Burgas, on the road E98 Burgas - Malko Tarnovo. The natural entrance (it is claimed that there is another entrance that occurred during the construction of the road) of the cave is located perpendicular to the road. It is narrow with a depth of about 2 meters.
