BlowHole Tangalle also called Hummanaya

Hummanaya is the only known blowhole in Sri Lanka and it may be the second largest blowhole in the world. Meaning of the word “Hummanaya” is the distance a sound of "hoo" can be heard.

It is located after Matara and Dikwella town in the Southern Province and at small fishing village called Kudawella

Hummanaya blowhole is sometimes spectacular and other times a fizzle. During the southwest monsoon (June is the best time), high seas can force water 23m up through a natural chimney in the rocks and then up to 18m in the air
