Gulstav Flak

Gulstav Flak isn't your typical tropical reef. This is Baltic diving, gritty and rewarding in its own way. We love Gulstav Flak for its sheer density of life, particularly the smaller, often overlooked species. You drop onto a rocky reef, scattered with boulders and patches of sand, usually in decent visibility for the area, around 8-15 metres on a good day. Keep your eyes peeled for the subtle stuff. We’ve spent entire dives just watching the dragonets and pipefish scooting along the bottom, masters of camouflage. Solenettes and dabs are almost invisible against the sand, and if you’re lucky, you might even catch a glimpse of a harbour porpoise patrolling the deeper sections. It’s a site that rewards slow, deliberate diving, perfect for macro enthusiasts or anyone who appreciates the quiet resilience of cold-water ecosystems. We’d suggest going in late summer or early autumn; the water is at its warmest then, and the light can be quite magical.
