Located near Kudawella on the southern coast, the Hummanaya Blow Hole is one of the largest natural blowholes in Sri Lanka and a spectacular sight. When ocean waves crash into underwater caves, water shoots high into the air through a rock formation, sometimes reaching over 25 meters. Visitors can experience this natural phenomenon best during high tide and rough seas. The surrounding cliffs and beaches add to the dramatic setting, making Hummanaya a unique coastal attraction worth exploring.
