    StandoutExceptional marine biodiversity

    The Portugal wreck, off the Cornish coast, is one we always suggest for those seeking a proper deep dive with a touch of history. This isn't a site for the faint-hearted or new divers; dropping down to 50 metres, it demands experience and careful planning. We’ve always been drawn to the sheer scale of this steamship, a significant vessel built in 1909 and torpedoed by U-113 in 1918. You descend onto a wreck that feels truly massive, its 71.9-metre length spread across the seabed. The bow and stern sections are particularly well-preserved, standing proud enough to offer swim-throughs into cargo holds that still feel eerie and cavernous. We love exploring the debris field around the main structure; it's here you often spot hefty conger eels peering from pipes and crevices, or lobsters scuttling away into the shadows. The sheer isolation of the Portugal at this depth means it attracts larger fish, too; we’ve seen impressive pollack schooling around the superstructure, their silver scales flashing in our torch beams. Best dived on slack water to avoid strong currents, this wreck delivers an authentic deep-sea exploration, leaving you with a genuine sense of its past.
