Why dive here
With 183+ marine species recorded in the area - including barracuda, dolphins, sea turtles, sperm whales and lionfish - Aldebaran Wreck offers some of Inner Islands's richest wreck diving. Water ranges 27-30°C, warmest March, April, May.
The Aldebaran Wreck, a deliberately scuttled fishing boat from 2008, sits upright on a sandy bottom, its mast reaching up towards the light. We love how the hull has been completely claimed by life in such a short time. You’ll find Montipora corals forming textured carpets along the decks, and the wheelhouse is often home to some chunky Argus Grouper watching you pass. Our favourite time to drop in is early morning, before the thermocline settles too deep, as that’s when we’ve seen the most activity with Dorado flashing by in the blue. At around 30 metres, it's a dive for those comfortable with depth, but the calm conditions usually mean you can take your time circling the 28-meter long vessel. Look closely for the smaller residents: Sandfish darting from cover, and we’ve found some surprisingly bold Dragonfish tucked into crevices. It’s an absorbing wreck dive, not for penetration, but for appreciating how quickly the ocean reclaims and repurposes.
Safety Notes
Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.
Aldebaran Wreck Wreck History

Vessel Type
fishing vessel
Cause
scuttled
Deliberately sunk in 2008, the Aldebaran Wreck is one of the premier deep dives in the Seychelles' Inner Islands. This 28-meter-long fishing boat was prepared and scuttled to create a thriving artificial reef, settling perfectly upright on a vast sandy plain. Its final resting position, with depths ranging from 28 to 40 meters, means this site is strictly for advanced divers with experience in deeper profiles and managing their bottom time effectively.
The wreck itself acts as an oasis in the sand, attracting a huge concentration of marine life. Divers are often greeted by large schools of fusiliers and snappers that cloud the superstructure. The sandy bottom is a prime location for spotting stingrays and eagle rays, while the wreck's nooks and crannies provide homes for moray eels, scorpionfish, and giant groupers. The Aldebaran is a testament to successful reef creation, offering a challenging and profoundly rewarding dive experience.
