Inside the spacious cave, which reaches a height of about 80 meters, you will find beautiful stalactites and stalagmites. To the east and south, there are prehistoric paintings depicting elephants and various types of boats. Additionally, this island grants concessions for bird nest harvesting. Typically, access to the interior is restricted to outsiders to avoid disturbing the swallows during their nesting period; however, on certain occasions, when the rock paintings are showcased, visitors are allowed to enter and appreciate these remarkable artworks.
