Why dive here
With 254+ marine species recorded in the area - including barracuda, dolphins, sea turtles, sperm whales and spinner dolphins - SIR JOHN JACKSON offers some of Trincomalee & East Coast's richest wreck diving. Water ranges 27-30°C, warmest April, May, October.
The Sir John Jackson, a steamship that went down in 1908, offers a pretty accessible wreck dive at just 5 metres deep. It’s sitting upright, which is always nice, and you can still make out a lot of its structure – the bow and stern are distinct, and we’ve spent time poking around the collapsed holds. Visibility varies, but when it’s good, you'll spot schools of fusiliers darting through the superstructure, and we’ve often seen various smaller reef fish tucked into the nooks and crannies. It's a relaxed dive, really good for photographers or anyone wanting to spend some quality bottom time getting to know a wreck without worrying about depth or tricky currents.
