JONIO
Why dive here
With 213+ marine species recorded in the area - including blue sharks, dolphins, great white sharks, hammerhead sharks and mobula rays (devil rays) - JONIO offers some of Corsica's richest wreck diving. Water ranges 15-28°C, warmest July, August, September.
The JONIO, a motor vessel that went down in 1972, rests upright at 34 metres. It’s a solid dive for those who appreciate a proper wreck rather than just some scattered debris. You can make out the bridge structure and a good section of the stern, which gives it a real sense of its former life. Over the decades, it’s become home to various Mediterranean species, with groupers often lurking in the deeper holds and schools of damselfish flitting around the railings. It’s a compelling site to explore, particularly if you're comfortable with deeper dives and want to spend some time piecing together its story underwater.
