Diving in Southern Sri Lanka: Mirissa and Unawatuna

Diving on Sri Lanka's south coast is all about warm water, a gentle entry into the underwater world, and the feeling of stepping into a living aquarium. Mirissa, Unawatuna and Hikkaduwa lie almost along the same stretch of coast, but each has its own character, which is what makes them so good for a diving trip.

Diving in Sri Lanka is warm water, a gentle introduction to the underwater world and a real adventure without extreme thrills. Mirissa, Unawatuna and Hikkaduwa lie close together, but each has its own character.
In Mirissa, you'll find calm reefs and comfortable depths for your first dives, plenty of bright tropical fish, sometimes moray eels, frogfish and octopuses, and on lucky days, larger sea visitors;
Unawatuna is known for its variety of dive sites, where reefs alternate with rocky outcrops and wrecks off the Galle coast;
Hikkaduwa is the more postcard-perfect choice, with coral gardens and frequent encounters with sea turtles in shallow water, so it is especially loved by anyone who wants plenty of living beauty from day one.
The tour is designed to feel confident for beginners and experienced divers alike: the price includes an English-speaking local instructor, all necessary equipment and two dives. The first is a training dive, where you calmly get used to breathing, technique and how it feels underwater. The second is a deeper, full underwater journey with beautiful locations and marine life all around.
In the end you get an easy, safe and very rich experience: the ocean feels truly alive, and these three towns let you choose your own atmosphere, from calm first steps in Mirissa to the classic reef scene of Hikkaduwa and the more varied routes of Unawatuna.

Thank you from the bottom of my heart for the tour you organized for me! Everything was organized really well: the transfer, the hotel, the flight tickets. Everything was clear. It was very nice that everyone I dealt with was so friendly. I hope this wasn't my last time in Vietnam, and if I come back, I'll contact only you! You are wonderful professionals! Thank you once again! Special thanks to your colleagues who organized all the transfers! Guys, well done!! All the drivers were great! I wish you all prosperity!! Irina Mulaleva

Our guide Jojo Oshan was wonderful, we loved everything, we were shown everything that was planned, in a very friendly and informative way. And special thanks to the driver who took us around, a true professional 🙌

Popular questions about diving in Sri Lanka

When is the best time to dive in Sri Lanka?

The island has two main dive areas: the south and west (Mirissa, Unawatuna, Hikkaduwa) are usually best from November to April, when the sea is calmer and visibility is higher; the east is best from May to October.

Is Sri Lanka suitable for beginner divers?

Yes. The south-west coast is known for calm conditions in season, warm water and reefs at comfortable depths, which is why first dives and beginner courses are often done here.

What can you see underwater when diving?

In the south and west you'll most often see tropical fish, coral reefs, moray eels and rays, while sea turtles are regularly spotted at Hikkaduwa and Unawatuna. The Unawatuna/Galle area also has wrecks and sunken structures.

Do I need a certificate to try diving?

For trial dives such as Discover Scuba Diving, you don't need a certificate. Your instructor guides you, and everything is explained on the beach and underwater. A certificate is required for independent or deeper dives without training.

How safe is diving, and what should I keep in mind?

Diving is safe when it is well organised: you dive only with an instructor or dive guide, and you go through a briefing and an equipment check. Outside the season, the sea can be rough and visibility low due to monsoon winds on some coasts. In those conditions, dive centres either close or move dives to the other side of the island.
