UNICORN - Cornwall & Devon
We’ve spent a fair few days diving around the UK, and Unicorn has always stuck with us. It’s a steamship, sunk back in 1923, sitting upright and pretty much intact at 48 metres. Dropping down onto her bow is quite the sight; you really get that sense of a vessel frozen in time, the mast still reaching up, though not quite to the surface these days. What we really love about this wreck is how approachable she feels despite the depth. At 27 metres long, she’s not huge, which means you can really take your time and explore her entire length on a single dive. We always find conger eels tucked into the deeper recesses of the holds, and the bridge area is often swarming with pollack. Visibility here can be surprisingly good on the right day, sometimes pushing 15 metres, which really lets you appreciate the ship’s structure. Our insider tip? Go for an early morning slack water dive, especially in late summer, and you might just get that golden light filtering down onto the deck. It’s a proper expedition dive, but for experienced wreck enthusiasts, it’s a brilliant window into maritime history.
