The St Tudwal wreck off the Scottish West Coast is proper wreck diving, no two ways about it. We’re talking about a fragmented cargo ship here, scattered across the seabed, rather than some intact museum piece. And that’s what makes it so good. Dropping down, the visibility can be fickle, but when it’s good, the sheer scale of the wreckage is impressive. You’re not just seeing a hull; you’re navigating through plates, girders, and machinery strewn about, creating these fantastic swim-throughs and hidden corners. It feels like an archaeological dig, discovering new sections each dive. Our favourite part is always the engine room, or what’s left of it. It’s usually swarming with conger eels, thick as your arm, peering out from the gloom. We’ve also spotted some enormous lobsters tucked into the nooks and crannies. This isn’t a colourful reef dive; it’s a dive for those who love history and the way the sea reclaims things. Expect cold water, and often a decent current, so this is definitely one for experienced divers who are comfortable in challenging conditions.
