Sri Lanka's Most Spectacular Wrecks
Love wreck diving? You're in for a treat! Sri Lanka boasts numerous wreck dive sites, here are the most renowned:
The British Sergeant Wreck
Located near Kayankerni, it's the country's most famous wreck. A steam-powered oil tanker that sank following an aerial raid by the Japanese military during the Second World War in 1942. The 122-meter-long wreck rests upside down at 24 meters depth. Venturing around or inside the ship's depths, you'll spot numerous fish species including barracudas, trevally, batfish, electric rays, emperors, scorpionfish, lionfish, as well as many nudibranchs and mollusks.
The Aircraft Carrier HMS Hermes
Another renowned wreck in Sri Lanka, the aircraft carrier HMS Hermes lies near Batticaloa. It sank at the same time as the British Sergeant. What makes it special? It's the world's first-ever aircraft carrier built! Due to its depth (50 m), this dive site is reserved for experienced divers only (PADI TecRec certified). The lucky ones might encounter eagle rays and blacktip reef sharks.
The MV Cordiality
Departing from Trincomalee, you can explore this impressive cargo ship. Loaded with limonite cargo, this vessel was seized by a commando unit from the Liberation Tigers of Tamil Eelam movement in 1997. At 18 meters deep and 198 meters long, you can dive this site multiple times without tiring. You'll encounter schools of tuna, fusiliers, snappers, and trevally, plus some flying gurnard, butterfly fish, and nudibranchs species… The good news? The MV Cordiality wreck is accessible to divers of all levels!
