ARENORTE NO.7
Why dive here
With 33+ marine species recorded in the area - including sperm whales - ARENORTE NO.7 offers some of Mar del Plata's richest wreck diving. Water ranges 10-21°C, warmest January, February, March.
Forget deep dives here; Arenorte No.7 is a different kind of adventure. This isn't about pelagics or technicolor reefs, it's about history you can touch, right in the shallows of Mar del Plata. We love how the hull of this old lighter vessel just barely breaks the surface on a calm day, giving you a peek at its ghostly form before you even get wet. At a maximum depth of two meters, this site is pure snorkel or free dive territory. We’d even suggest a strong swimmer could spend an hour just exploring its skeletal remains from above. You’ll weave through rusted beams and mangled plates, feeling the cool surge against your legs as small fish dart between the shadows. It's a surreal experience, almost like swimming through a submerged industrial sculpture. Keep an eye out for crabs scuttling over the barnacle-encrusted metal and the occasional small octopus peeking from a crevice. It’s definitely our pick for a low-key afternoon when the wind dies down and you’re looking for something uniquely Mar del Plata.
