    The Frau Anna Katharina is a Scapa Flow classic, a solid dive that often gets overlooked in favour of the bigger German High Seas Fleet wrecks. We love it for its accessibility and just how much you can explore here without feeling rushed. This Blockship, scuttled in 1915, now lies neatly upright, its bow often piercing the surface at low tide, which makes for a dramatic entry. Drop down and you're immediately into the superstructure, with plenty of swim-throughs and large cargo holds to poke around in. Light filters in, illuminating huge plumose anemones that carpet the bulkheads, their white tentacles swaying gently in the slight current. Look closer and you'll spot scuttling crabs and blennies peeking from crevices. It’s a fantastic site for photographers and those who appreciate the history, but equally rewarding for divers who just want a relaxed rummage around a well-preserved wreck. Our tip: go at slack tide for the best visibility; the Flow can get a bit soupy at other times.

    Safety Notes

    Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.
