Hummanaya Blowhole

Nestled in the Southern Province of Sri Lanka, the Hummanaya Blowhole is a coastal formation that draws genuine curiosity — not just from tourists, but from anyone who's seen what happens when the ocean forces itself through rock. As the only known blowhole in Sri Lanka and one of the largest in the world, it's worth the short trip.

A blowhole forms when seawater is forced through a narrow opening under pressure — the result of erosion over long periods. The height and frequency of the jet depend on tides, currents, and wind. At Hummanaya, sprays can reach 25 to 30 meters on a strong swell.

The name Hummanaya comes from the Sinhala word for the sound — hoo — audible from a distance when the blowhole is active.

The site is located about 1 km from the small fishing village of Kudawella (Google Maps), approximately 10 km or a 20-minute tuk-tuk ride from Aliya Watunu Hena. The walk from the village involves a short ascent over a rocky outcrop, with good views of the Indian Ocean on the way.

The blowhole fires every few minutes when conditions are right. The slow-motion effect — if you're filming — is worth the patience.

There's a small visitors' information center on marine life and a purpose-built viewing platform. Admission: LKR 300 per person. Not wheelchair accessible due to stairs.

Local legend holds that a giant sea serpent lives beneath the blowhole, and that its breath creates the jets of water. The fishermen of Kudawella have lived with this sound for generations.
