6 Iconic Diving and Snorkelling Sites in Sri Lanka - Adventure Beneath the Waves

Situated along the southwest coast of Sri Lanka, Hikkaduwa National Park stands as one of the island nation's two Marine National Parks. Within its confines lies the main reef, nestled within a sheltered lagoon boasting an average depth of 5 meters, making it an ideal spot for first-time snorkelers. An endemic coral species of Sri Lanka called Poritesdessilveri thrive in this habitat. For those seeking deeper adventures, Hikkaduwa offers the opportunity to explore the remnants of the SS Conch, a steam-powered tanker built in 1892 and hailed as one of the world's first oil tankers. A cabin in the shipwreck still is intact and visibility is high since the seabed is rocky.

Sri Lanka's largest coral reef and protected marine area, the Bar Reef, lies just 2 km off the coast of Kalpitiya. This location serves as an excellent starting point for beginners eager to experience Diving in Sri Lanka, as the shallow waters ensure safe and accessible dives. The reef itself is a vibrant ecosystem, boasting around 150 species of coral and over 280 species of fish. If you are lucky, you might even spot an octopus. At greater depths, divers can share a dive with reef sharks and manta rays.

The wreck of HMS Hermes has historical significance because it was the world's first ship built as an aircraft carrier by the Royal British Navy during World War I. It was launched in World War II and was sunk by Japanese bombers near Sri Lanka's east coast. You can still see its emergency light balls, glasses in the windows and an almost intact control tower. If you take a taxi from the airport to Batticaloa, it will take about 7 to 8 hours to get there. However, with an airplane service like Cinnamon Air, you'll be there in less than an hour.

Negombo stands out as an excellent destination for snorkeling and diving enthusiasts alike. Among its array of popular diving spots are Barracuda Point, Derana Gala and the remnants of a World War II fighter aircraft called 'Ahasyatra Gala' by locals, which translates to Airplane Rock. Fish species you may observe in Negombo coral reefs include barracuda, trevallies, fusiliers, blue-striped snappers, honeycomb morays and rays. With its rich underwater biodiversity and convenient proximity to the airport, Negombo promises an unforgettable adventure just a short drive away.

The best time to visit Pigeon Island in Trincomalee is from April to September when the seas are calmer. As a marine national park, Pigeon Island boasts breathtaking coral reefs and a diverse array of exotic marine species including the Blacktip Reef Shark, Hawksbill Turtle, and Green Turtle, alongside vibrantly colored coral fish. After your underwater escapades, you can kick back and relax on the pristine shores of Pigeon Island. With its picture-perfect beaches and breathtaking views, it's the perfect place to unwind after a day of snorkeling or diving thrills. 

These reefs nestled along the Southeast coast of Sri Lanka are perfect for seasoned divers seeking thrills. The best time to dive here is between March and mid-April. Diving outside this window is discouraged due to the presence of strong currents. You can explore an impressive array of marine species including tuna, angelfish, spadefish, grouper, porpoise, grey sharks, humphead wrasses, snappers and rays. One of the highlights of diving in the Great Basses Reef is the opportunity to explore a fascinating shipwreck dating back to the 18th century. The ship belonged to Mughal Emperor Aurangzeb whose father built the Taj Mahal in India.
