ONIX
Why dive here
With 33+ marine species recorded in the area - including sperm whales - ONIX offers some of Mar del Plata's richest wreck diving. Water ranges 10-21°C, warmest January, February, March.
The ONIX wreck in Mar del Plata is a shallow dive, maxing out at 7m. It’s a classified dangerous wreck, so we’d suggest good buoyancy control and a healthy respect for its structure. You can explore the bow and stern sections, which offer some interesting swim-throughs, now home to cormorants and various small fish sheltering in the nooks. It's a solid choice for wreck enthusiasts looking for something different, particularly those who appreciate a good story behind a vessel.
