The Bay in Pasikudah is ideal for diving, and the most prominent location is the wreck site of the British aircraft carrier HMS Hermes. HMS Hermes served during World War II and dropped into the sea off Batticaloa in 1942 during a Raid, attempting to offset Japanese attacks. It is probably the most prominent wreck on the island. The site has several significant artefacts lying in its watery grave, along with extensive marine life that has made the wreckage site their home. You will undoubtedly catch a glimpse of vast shoals of snapper, barracudas, tuna, grouper, nudibranchs and crabs.
