Okay, so a wreck at 2m? AGRION isn't your deep, dramatic plunge into history, but it's exactly why we love it. This trawler, aground on Les Etocs, is an exercise in accessible wreck diving, especially when the conditions are just right. We’re talking about a site that feels more like a living, breathing art installation than a typical wreck. Head out on a calm day, ideally on a neap tide, and you’ll find the AGRION’s crumpled form just beneath the surface. Sunlight slices through the water, illuminating the hull’s ripped plates and the skeletal superstructure. It’s shallow enough for even a keen snorkeller to appreciate, but divers get to spend time really poking around. Look for the glint of small blennies darting into crevices, or a feathery anemone waving from a shadowed corner. The whole site hums with the gentle surge, and we always find ourselves spotting something new – a cluster of jewel anenomes, or a velvet crab scuttling across rusted metal. It’s less about penetration and more about savouring the interaction between steel and the sea, perfect for an easy second dive or when you just want to soak up some underwater atmosphere without the pressure.

AGRION Wreck History

Year Sunk

1975

Vessel Type

fishing vessel

Cause

grounding

The fishing trawler "AGRION" had a dramatic and final end to its career on February 9, 1975. While operating near the port of Guilvinec in France, not far from its home waters off Cornwall and Devon, the vessel ran hard aground on the notorious rocks of Les Etocs. This type of incident was a constant fear for mariners in these treacherous coastal waters, where submerged reefs and powerful currents could quickly spell disaster. The "AGRION" was lost to the sea, broken apart by the relentless force of the waves.

Lying in a mere 2 meters of water, the "AGRION" is less of a traditional scuba dive and more of a shallow-water exploration for snorkelers, freedivers, or divers looking for an interesting site during a surface interval. The wreck is so shallow that portions of its hull or superstructure remain visible above the water at low tide. Divers can explore the scattered wreckage field, which has been flattened and dispersed by decades of surge and storms. It serves as a stark, tangible reminder of the power of the sea.
