DONA TOMASA

Diving Mar del Plata isn't about tropical reefs, it's about history and the surprising life that clings to it. The *Doña Tomasa* is a perfect example. She was a light vessel, sunk quite intentionally we think, to form a breakwater. Now, at a maximum depth of just four metres, she’s a fantastic, easy dive, especially for those new to wreck exploration or anyone just wanting a relaxing hour underwater. What we love about the *Tomasa* is how accessible she is. You can spend ages poking around her hull, peering into the shadows where parts of the superstructure remain. Visibility here usually sits around 5-10 metres, sometimes a bit more after a calm spell. You’ll find plenty of small crabs scuttling amongst the growth, nudibranchs slowly making their way across the metal, and various small fish darting in and out of the crevices. It’s a completely different vibe from a deep wreck; here, sunlight penetrates everywhere, illuminating the rust and the surprising amount of green algae that forms the base of the food chain. It’s not a challenging dive, but it's genuinely rewarding to see how a piece of industrial history becomes a home.
