Most travellers on the south coast stop at Mirissa for the whales and Galle for the fort, then head home. They drive straight past a rocky stretch of coast near Dikwella where the sea shoots into the air with a roar you can hear long before you see it.
That is Hummanaya Blowhole, the only known blowhole in Sri Lanka. It is small, free of tour buses, and on the right day it is genuinely impressive. On the wrong day it is a hiss and a damp rock.
This guide covers what Hummanaya Blowhole is, the best time to visit, how to get there, the entry fee, and how to stay safe on the rocks.
What is Hummanaya Blowhole?
Hummanaya Blowhole is a natural blowhole on the coast at Kudawella, a fishing village near Dikwella in the Matara district. It is the only blowhole in Sri Lanka that is widely known and visited.
It is often described as the second largest blowhole in the world. That claim is repeated everywhere but rarely sourced, so we treat it as local pride, not a measured fact.
A blowhole forms when waves force seawater through a narrow opening in the rock. At Hummanaya, seawater rushes through a submerged cavern and is pushed upwards. On a strong day the spray can reach around 30 metres.
Why is it called Hummanaya?
The name comes from the sound. "Hummanaya" imitates the deep "hoo" you can hear from a distance when the blowhole is active.
Visitors describe quiet stretches, then a rumble like faraway thunder as pressure builds, then the hiss of spray high above the cliff. You often hear it from the path before you reach the rocks.
Best time to visit Hummanaya Blowhole
The blowhole depends entirely on waves, so the sea decides everything.
- Best season: the southwest monsoon, roughly May to August, when the sea is rough and the blowhole is most active. Locals say anywhere from April to October can work.
- Best time of day: mornings, when the sea tends to be rougher. Some visitors also recommend high tide, so check a local tide table.
- Off season (November to April): the sea is calmer and the show is much smaller. You will still hear it and see some spray, but nothing dramatic.
Online ratings are mixed. Most of the low scores come from people who arrived on a calm day expecting a geyser. If the sea looks flat when you wake up, decide whether the trip is worth it.
Where is Hummanaya Blowhole?
Hummanaya Blowhole is near Kudawella, just east of Dikwella town, on Sri Lanka's south coast. It is about 22 km east of Matara and roughly 212 km from Colombo, around 3.5 hours by road via the Southern Expressway.
Search for "Hummanaya Blow Hole" in your maps app. Locals also call the area the Kudawella blowhole, and listings sometimes place it under Dikwella or Kudawella.
Opening hours and entry fee
It is an open coastal site, so there are no strict gates. Listings show roughly 8:00 am to 7:00 pm, and daylight is the sensible limit for safety.
There is a small entry fee for foreign visitors. Reports vary, and one recent visitor paid 250 LKR per person, while locals pay far less. Bring small notes in cash and treat any figure as a guide, because fees change. We have not set a fixed price here for that reason.
How to get to Hummanaya Blowhole
Pass Dikwella heading east, then turn right at Kudawella and follow the road for about 1.1 km. Local residents will offer to look after your vehicle for a small fee. From there it is a walk of around 20 minutes on shallow steps, past small kiosks selling cold drinks and fried fish.
From Matara
Roughly 30 to 40 minutes by tuk tuk or car, depending on traffic. You can combine it with Weherahena Temple on the way.
From Mirissa and Weligama
Allow about an hour from Mirissa and an hour or more from Weligama by tuk tuk or taxi. A private driver is the easiest option.
From Dikwella, Hiriketiya and Tangalle
Dikwella and Hiriketiya are a short hop, usually 10 to 20 minutes. From Tangalle, allow around 30 to 40 minutes.
By bus
Take a local bus from Matara towards Dikwella and tell the conductor you want the blowhole. You will need a short tuk tuk ride from the main road.
Is Hummanaya Blowhole worth visiting?
Yes, if you are staying anywhere between Tangalle and Matara, you are visiting in the monsoon months, and you like natural spectacles that most travellers skip. It takes about an hour including the walk, so it fits easily into a Dikwella day.
Skip it if the sea is flat, if you only have a short time on the coast, or if you expect a big photo moment on a day the sea is not cooperating.
Safety at Hummanaya Blowhole
This is open ocean on sharp, wet rock.
- Stay behind any barrier or marked path and keep well back from the edge.
- Never turn your back on the sea. Waves can surge higher than you expect.
- Do not go near the opening for a photo, and do not let children climb the rocks.
- If the sea looks unusually rough, watch from higher ground.
The view is just as good from a few steps back. Nothing is worth a bad fall.
What to pair it with: things to do in Dikwella
Hummanaya works best as part of a half-day around Dikwella:
- Wewurukannala Temple. A 160-ft seated Buddha dating to the late 1700s, with the "Tunnel of Hell" corridor of life-sized figures. One visitor was upset to see a chained elephant at the temple, so make your own call about whether to visit.
- Dikwella fishing harbour. Watch the boats come in.
- Hiriketiya and Goyambokka. Both are close for a swim or lunch afterwards.
- A café stop at Talalla. Mutts Street Dog Café is a short drive back towards Matara and funds street dog care.
- A tuk tuk tour. Some operators run a 4-hour countryside tour from Dikwella and Hiriketiya that includes the blowhole.
A few things we would know before visiting
Do not go on a flat, calm day expecting a geyser.
Check the sea first. If it is calm, the blowhole will be small. Rough mornings in the southwest monsoon are the best bet.
Do not cross barriers or climb out onto the rocks.
The rocks are wet, uneven and sharp, and waves surge without warning.
Do not turn your back on the sea.
Face the water at all times, especially when taking photos.
Do not rely on a listed fee or opening time.
Both change. Carry small notes in cash and confirm locally.
Do not wear flip flops.
Shoes with grip make the walk and the rocks much safer.

Final thoughts
Most of the south coast is beaches, cafés and temples. Hummanaya is one of the few places where the sea is the attraction, and where you can stand a few steps back and feel it.
Go in the monsoon, go in the morning, wear proper shoes and keep your distance from the edge.
If the sea is flat, skip it and spend the time at Hiriketiya instead. If it is rough, it is one of the best free stops on the coast.
