TREWORLAS - Tobago

Treworlas is a serious wreck dive, and we mean serious. This isn’t some artificial reef dropped for divers; this is a piece of history, sunk by a U-boat in 1942. Lying at 34 metres, she’s a deep dive, pushing into deco territory if you’re not careful, so bring your A-game and gas planning. What makes her special? Her sheer size. At over 120 metres long, you can spend multiple dives here and still not see it all. The bow section, where we usually start, is heavily encrusted with sponges and hard corals, creating overhangs where schooling snappers lurk. Swim along the deck line and you’ll pass colossal boilers and engine components, now home to moray eels and the occasional nurse shark tucked into a shadowy corner. Visibility can be a bit variable here, depending on the current, but when it’s good, the light penetrating the holds is ethereal, revealing the wreck’s skeletal structure. This is for experienced wreck divers, those who appreciate the somber beauty of a submerged vessel with a story to tell. Expect strong currents sometimes; it’s an exposed site. Our favourite time to dive Treworlas is early morning, before any potential boat traffic kicks up the silt and when the resident fish life is most active.
