Hummanaya stands as a unique natural wonder in Sri Lanka, renowned as the sole known blowhole in the country and potentially ranking as the second largest blowhole globally. The name ‘Hummanaya’ derives from the distance over which the sound of ‘hoo’ can be heard, a fitting moniker for a spectacle that beckons visitors with its distinctive ho-ho-hoo resonance.

Nestled amidst rocky cliffs in the Kudawella Blowhole area, Hummanaya captivates with its dramatic display of nature’s power. A solitary rock boulder amidst the rugged cliffs features a central breakage, through which the relentless force of the sea unleashes its might. When waves crash against the rock, water surges through the aperture, shooting several meters into the air in a breathtaking spectacle. This phenomenon requires the convergence of two powerful waves from different directions, amplified by windy conditions to create the awe-inspiring jet of water.

Hummanaya’s allure is particularly pronounced during the monsoon rain season, shrouding the surroundings in an aura of mystery and intrigue. Visitors are often left spellbound by the sight, eagerly attempting to capture the exhilarating experience through photography, although the task proves challenging amidst the tumultuous environment. Care should be taken, especially when accompanied by children, as the site is anything but tranquil. In times of rough seas, the water column can soar to impressive heights of 25 to 30 meters, adding to the dynamic energy of the location.

The significance of Hummanaya is not lost on historians and travelers, with R.L. Brohier documenting its magnificence in his records of Ceylon back in 1965. His vivid description encapsulates the mesmerizing essence of Hummanaya, where the thunderous roar of the sea culminates in a dazzling eruption of water, leaving onlookers awestruck by the raw power of nature.
