From the time of the Tamil Kingdom to the rip-roaring watersports events of just last summer, life in Kalpitiya has always revolved around the sea.

While the town has long been known as a world-class kiteboarding destination, diving is now firmly on its way to becoming one of the most exciting things to do in Kalpitiya’s great outdoors.


For one, it’s easily one of the best (not to mention the most wildly underrated) diving locations on this side of the Indian Ocean.

The marine life is insanely rich and diverse.

The coral reefs are beautifully complex.

There’s a long, reliable season that offers perfect conditions for exploring the underwater world.

And best of all, there’s a bunch of local schools and divers who are mega enthusiastic about spreading their love for this little patch of ocean paradise.

So, are you ready to learn the basics about the Kalpitiya diving scene? Let’s jump right in:

Kalpitiya diving: what to expect

Just an hour off the coast from Kalpitiya, the 300 kilometer long Bar Reef is the largest reef system in Sri Lanka and a protected marine sanctuary.

Bar Reef is home to an impressive 156 types of coral and 283 different species of tropical fish, making it one of the most diverse marine ecosystems in this part of the Indian Ocean. Unsurprisingly, Bar Reef is the most popular spot for diving in Kalpitiya.

With an average depth of 3 meters, diving at Bar Reef could bring you face to face with black-tip and white-tip reef sharks, manta rays; green, hawksbill, or olive ridley turtles, and more kinds of crazy looking tropical fish than you could ever hope to dream up on your own.

Sri Lankan maritime experts, SLAM, reckon the next best spots Kalpitiya diving spots are Talawila Reef, Bulldog Reef, Davey’s Reef, Kalpitiya Ridge, Trevally Pass, and Moray Ridge.

Best season for diving in Kalpitiya

The Kalpitiya diving season begins in late November and stretches on into early May (though this can vary by a couple of weeks either end, depending on the exact dive location and type of dive you want to do).

During this time, primo wind and water conditions roll in to Sri Lanka’s west coast- making it ideal for scuba diving and snorkeling (keep in mind to get yourself one of the best snorkel masks for extra security). You’ll experience minimal wind, few currents, and relatively calm water conditions.

Conveniently, this also coincides with whale and dolphin watching season.

Around Kalpitiya, you’re most likely to catch a glimpse of some humpback whales, minke whales, sperm whales, melon-headed whales, or even the elusive blue whale- the largest mammal on earth.

Kalpitiya diving conditions

Since it was declared a Marine Sanctuary in 1992, Bar Reef has enjoyed some of the greatest biodiversity around the Gulf of Mannar- have a peek at this video from Ocean Lanka and see for yourself:

The water temperatures in Kalpitiya rarely drop below 23.5 degrees Celsius (75 F) so you won’t need a wetsuit- even during the ‘winter’ months. That being said, some like to wear a thin suit to protect their skin from coral.

The waters around Kalpitiya aren’t heavily affected by any underwater currents. However, they are affected by the tides: two high water and two low. In general, visibility ranges from 10-25 meters, according to Kalpitiya Diving Center.

As for the condition of the coral:

At Kalpitiya’s most popular dive site, Bar Reef, some of the shallow reef has been damaged by predatory crown-of-thorns starfish, dynamite fishing, unregulated coral mining, and stray boat anchors; but the deepest coral remain in near pristine condition.

On top of this, ROAR reports that Bar Reef has sadly not been immune to the plights of global warming.

“In 1998, the Bar Reef in Kalpitiya underwent a bleaching event due to a rise in the temperature of the Indian Ocean. Once again in 2016, the Bar Reef faced a similar incident during the ‘Great Indian Ocean Bleaching Event’.”
