Hummanaya is Sri Lanka's only blowhole and the world's second-largest, where sea pressure sends a roaring "hoo" and a towering jet of water skyward through a cliffside village channel.

Why visit Hummanaya Blow Hole

• Sri Lanka's Only Known Blowhole: Hummanaya is the only blowhole in Sri Lanka and is considered the second-largest in the world. Its name comes from the "hoo" sound it makes when active.
• Geological Marvel: The blowhole is a natural phenomenon where seawater rushes through a submerged cavern and is forcefully pushed upward, creating a powerful jet of water. The height and timing of the sprays depend on the tides and wave formations.
• Impressive Water Spouts: The water fountain can shoot up to a height of 25 to 30 meters (82 to 98 feet), with some reports of it reaching as high as 120 feet.
• Best Time to Visit: The most dramatic water spouts occur during the southwest monsoon season, from May to September. It's recommended to visit in the early morning or late afternoon to avoid the midday heat and larger crowds.
• Local Significance: The blowhole is an important part of the local community's culture and daily life, serving as a point of reference for fishermen. It has been a local marvel for centuries before gaining popularity as a tourist attraction.
