Hummanaya (Blowhole)

Hummanaya is a natural blowhole on the rocky coast at Kudawella, near Dikwella on the south coast. When a wave rushes into a narrow gap in the cliffs, the pressure forces water up through a crack and throws spray high into the air. The name comes from the "hoo" sound it makes.

What you see

On a good day the spray reaches many metres high, with a loud roar, and the plume drifts across the viewing area. On a calm day you may only see small bursts. It is unpredictable, so be patient: big shots come every few minutes when the swell is right, and less often when it is not.

When to go

The blowhole is strongest when the sea is rough, which on this coast means the south-west monsoon, roughly May to September. In the calmer season, November to April, eruptions are smaller and less frequent. High tide usually helps.

Entry

A small entrance fee is collected at the site. Amounts change, so check on arrival.

How long it takes

Thirty minutes to an hour, including the walk down.

Getting there

Hummanaya is a few kilometres from Dikwella, signposted off the coast road. From the car park, a path and steps lead down past houses and stalls to the viewing platform. It is about 30 minutes from Tangalle and 20 minutes from Dikwella.

Practical tips

• Stay behind the barriers; rocks are slippery and waves are powerful.
• Protect cameras and phones from the spray.
• Wear shoes with grip for the steps.

Combine it with Weherahena temple or a swim at Dikwella beach. See things to do in Dikwella and Dikwella hotels.
