    The Ciudad de Gualeguaychú, just off Mar del Plata, is a real favourite of ours for a quick wreck dive. At a shallow 12 metres, it’s a site that feels accessible to most divers, and it’s a brilliant introduction to wreck diving in the area. We love how much of the old transport vessel is still intact; you can really make out the superstructure and the cargo holds, even after all these years. Dropping down, the first thing you notice is the way the light filters through the waves, dappling across the metal hulk. It’s got a wonderfully eerie, almost ghostly feel. The wreck itself is covered in a surprisingly thick carpet of mussels and anenomes, which makes for some vivid texture against the rust. Keep an eye out for the shoals of silversides that often hover above the deck; they flash like quicksilver when you swim through them. We’ve spotted conger eels tucked into crevices, too, and on a good day, the visibility lets you appreciate the sheer scale of the vessel. Our pick for an insider tip? Dive this one in the morning. The currents are often calmer, and the light penetration is just beautiful.
