Why dive here
With 46+ marine species recorded in the area - including dolphins, sea turtles and cuttlefish - M.L. 558 offers some of Istria Peninsula's richest wreck diving. Water ranges 12-26°C, warmest July, August, September.
The M.L. 558 is a peculiar wreck, often overlooked for Istria's bigger names, but we think it’s a real treat. This British motor launch went down in 1945, reportedly mined. It sits upright at 32 metres, surprisingly intact. Our favourite part is navigating the superstructure; you can really get a feel for its original layout. The wheelhouse is especially atmospheric, with light filtering through the open spaces, casting long shadows. Inside, you’ll often find conger eels coiled up, their heads peeking out, watching you pass. Around the deck, schools of damselfish flit amongst the rusting metal, and we’ve seen some decent scorpionfish camouflaged on the hull. It’s not a coral garden by any stretch, but the marine growth clinging to the metalwork is fascinating. We'd suggest aiming for a calm day; while the wreck itself isn’t deep, the visibility can shift. It’s a great site for divers who appreciate history and a bit of exploration without strong currents.
