THYRA - Scapa Flow, Orkney

The *Thyra* is an accessible wreck, sitting shallow with its deck just a couple of metres below the surface. We've always found it a great spot for a relaxed dive, especially when the weather rolls in and other sites are a no-go. You'll trace the outline of a substantial steamship, built in 1899, with both boilers and parts of her triple-expansion engine still visible. Despite the shallow depth, the *Thyra* attracts its share of critters; often, we'll spot wrasse darting through the rusted plates and the occasional inquisitive crab tucked into a crevice. It’s perfect for divers looking for a leisurely exploration of history without the challenge of deeper wrecks.
