    Cerro Cora is a quirky wreck, tucked away just off Mar del Plata. We love it because it’s so approachable, sitting shallow at only 11 metres. This makes it a perfect first wreck dive or a nice multi-dive day if you’re keen on photography. The wreck itself is an old barge, sunk back in ‘76, though some records say it went down in Buenos Aires. Either way, it’s been on the seabed long enough to feel like part of the furniture. The structure is quite broken up now, but that just means more nooks and crannies for life to hide in. You’ll find plenty of small crabs scuttling over the plates and schools of silversides shimmering through the gaps. Look closely and you might spot a blenny peering out from a crevice. We’ve even seen a small conger eel tucked away in a shadowed corner on a few occasions. Visibility can be a bit hit-or-miss here, so we’d suggest going on a calm day, especially after a few days without strong southerly winds. That’s when you’ll get the best light filtering down onto the old metal, really bringing out the rust colours and the green algae bloom. It’s not a dramatic drop-off, more of a gentle exploration, but it’s an honest, rewarding dive.
