Hummanaya, Natural blowhole in Kudawella, Sri Lanka
The Hummanaya blowhole releases powerful jets of seawater through a natural rock crevice, reaching heights of 25 meters above the rocky coastline.
Natural geological processes over thousands of years have shaped this coastal formation, which fishermen historically used as a navigational reference point.
Local residents named the formation Hummanaya after the distinct sound produced when water rushes through the underground cavern system.
The viewing platform provides clear observation points of the water display, with the most frequent eruptions occurring during the November to April period.
This geological formation stands as the second largest blowhole in the world and the only known example in Sri Lanka.
