HELIOS
Why dive here
With 33+ marine species recorded in the area - including sperm whales - HELIOS offers some of Mar del Plata's richest wreck diving. Water ranges 10-21°C, warmest January, February, March.
Helios, just off the coast of Mar del Plata, is a shallow wreck, only three metres deep, making it a truly accessible dive. This isn't a site for depth hunters, but it’s perfect for those who love history and easy exploration. We love how the wreck’s bones, scattered across the sandy bottom, create a skeletal garden for the local marine life. It’s an old fishing trawler, reportedly sunk by a storm decades ago, and the sea has really claimed it. You’ll spend your time here exploring the broken hull plates and the remnants of the superstructure, now completely encrusted. Look closely and you'll spot crabs scuttling amongst the growth and schools of small silversides darting in and out of the shadows. The light here, even on an overcast day, filters down beautifully, giving the wreck a slightly eerie, almost ghostly feel. Our favourite tip for Helios is to bring a good camera, especially on a sunny morning – the light play over the wreck is fantastic, and the macro opportunities are everywhere. It’s a gentle, relaxing dive, ideal for new divers or anyone wanting a chilled-out hour underwater without battling currents or depth.
