It is located at the western foot of peninsula. There is a 50 m passage at the entrance. After the passage, there comes a cylindrical cavity. This leads to the basement of the cave. The stalactite and stalagmites inside the cave were formed in 15 thousand years. Besides its fascinating beauty, the cave is famous with its air, which is beneficial to asthmatic patients. Following the rumours that asthmatic benefited from breathing the air in the cave, scientists analyzed a sample of the air to verify the fact that the air was indeed beneficial to patients suffering from non-allergic asthma. They found that the air in the cave contains 10 to 12 times more carbon dioxide than normal air and has 95 % humidity. Temperature in the cave is 22 degrees centigrade. Both the radioactivity and ionization in the cave may contribute to the benefits derived from breathing the air in the cave.
