ALDEBARAN - Inner Islands
We’ve spent a fair bit of time exploring the Aldebaran and it’s become one of our favourite wreck dives in the Inner Islands. This ex-longliner fishing vessel sits upright at 26 metres, a proper, intact wreck you can actually get into. You’ll find the wheelhouse still mostly there, and for those comfortable with overhead environments, the engine room is a tight squeeze but worth the effort. What we really love about the Aldebaran is the way the marine life has completely embraced it. Schools of fusiliers are so thick around the mast and superstructure, they often block out the light, creating this flickering, silver curtain. Look closely among the nooks and crannies – you’ll often spot massive groupers lurking, and we’ve had some cracking encounters with giant trevally circling the bow. On one dive, a napoleon wrasse, bold as brass, came right up to us near the stern. It's a dive that really suits those who enjoy the character of a real wreck, not just a pile of rubble, and the sense of discovery that comes with poking around inside.

- Cause

The Aldebaran is an artificial reef sunk to enhance the marine ecosystem and provide a unique destination for divers in the Seychelles. This former long-liner fishing vessel now rests on the seabed, its working life over and its new purpose to shelter and nurture ocean life. Its designation as a 'Dangerous Wreck' is a caution to divers, likely due to the presence of old fishing nets, lines, or sharp, deteriorating metalwork that require careful navigation and excellent buoyancy control. For the properly trained and equipped diver, it offers a compact and intriguing site to explore, from the wheelhouse to the open decks where the day's catch was once processed.
