The “Hummanaya – Blow Hole” is a natural fountain, caused when sea water rushes through a submerged cavern and is pushed upwards. Hummanaya is located on the southern Sri Lankan coastal fishing village called “Kudawella”, in between Dikwella & Tangalle.
The ocean water flows underneath the shore, and then comes out of this hole due to pressure with a humming sound. The spray is often as high as 25 meters, giving on lookers a sea bath on land
