Map of Sri Lanka Dive

Sri Lanka, the jewel of the Indian Ocean, was proclaimed by Marco Polo to be amongst the finest islands on earth.

Sri Lanka is home to seven UNESCO World Heritage Sites. Six of these are testament to a civilization with over 2,000 years of recorded history while a seventh natural site boasts some of the highest biodiversity in the world. These sites showcase the island's rich history and contribution to civilization. The largest of these sites are located in the 'cultural triangle', an area that links the ancient capitals of Anuradhapura, Polonnaruwa and Kandy.

With its exciting cultural past, Sri Lanka (formerly known as Ceylon) has a rich maritime history. According to historical records it is estimated that there are over 200 shipwrecks around the coast of Sri Lanka. Five hundred years of trade, commerce, conflict and war from the times of the Portuguese, Dutch and the British resulted in vast amount of shipping traffic around the coast, ensuring a diverse selection and large number of wrecks.

Without a doubt, one of the most outstanding wreck dives in the world can be found in Sri Lanka. HMS Hermes has recently become available for technically trained divers to explore. At dawn, on 9 April 1942, in the Indian Ocean just off the coast of Batticaloa in eastern Sri Lanka, the 167 metre long, 12,900 ton aircraft carrier HMS Hermes, was attacked in a devastating raid by 70 Japanese aircraft. Taking 40 hits in just 10 minutes, HMS Hermes capsized and disappeared beneath the waves, with the loss of 307 men.

With 12 National Parks and 52 Sanctuaries, the island of Sri Lanka is one of the most biologically diverse countries in Asia. A safari offers the chance to see some of Sri Lanka's 92 mammals, of which 16 are endemic.

  • Geographical Information

  • Filled with cultural and natural treasures, the island encompasses magnificent landscapes, beautiful beaches, abundant wildlife and ancient art and architecture. Over 1,300 km of beach surround the island, from established tourist destinations of the southern coast to the less-visited beaches of the north and east.

    On the east coast of Sri Lanka is the city of Batticaloa which sits on a flat coastal plain, bordered by the Indian Ocean, several large shallow lagoons and a 4 kilometre stretch of sandy beach. Batticaloa is about 300 kilometres east north east from the capital city of Colombo and 111 kilometres south by south east of Trincomalee. Getting to Batticaloa (Batti) from Colombo is generally a minimum 6 hour affair. The journey is as exciting as the destination. From the ancient kingdom of Polonnaruwa, the road to Batti is tortuous, winding upon an arid terrain covered with bush and occasional stray cattle. Sightings of  wild herds of elephants, peacocks, deer and mongoose is a common occurrence.

  • Scuba Diving in Sri Lanka

    HMS Hermes, located just 8 kilometres (30 minute boat ride) off the coast, is just one of the wrecks that forms a divers' paradise around Batticaloa. Sunken ships and other detritus of war, litter the sandy bottom along the coast, including remains from more recent conflicts. Until 2008, it was only possible to dive the east coast if you were accompanied by the Sri Lankan navy.

    But now, more than sixty years after sinking, the area has been opened to tourism and HMS Hermes has finally become available for technically trained divers to explore. One of just three aircraft carriers accessible to divers (the USS Oriskany located in Florida, and the USS Saratoga located in Bikini Atoll), HMS Hermes is unique in that she was the only one sunk in battle. This is without doubt, one of the most outstanding wreck dives in the world, with incredible visibility and abundant marine life.

    We are very excited to be able to offer divers the unique opportunity to dive this remarkable wreck.
