The Wreck of the Caitloch, sitting off the Scottish west coast, isn't about tropical colours. It's about atmosphere, about history you can touch, and about that particular chill in the water that lets you know you're somewhere wild and elemental. We love it because it's a proper wreck dive, not just a pile of scattered plates. You can still make out the ship's lines, the upright bow cutting a dark silhouette against the murk, and the holds that beg for exploration. This is a dive for those who appreciate the quiet drama of temperate waters. Expect to find walls of plumose anemones, their white frills swaying gently, and big ling peering out from shadowy crevices. The penetration is manageable in parts, giving you a real sense of being inside the ship, and we’ve often found dogfish tucked away in the darker corners. Visibility can be a challenge here, sometimes dropping to a few metres, but that just adds to the adventure. Our top tip? Go on a slack tide, otherwise, you'll be fighting a current that’ll make you feel like you’re doing a treadmill workout. It’s a site that rewards patience and a good torch.
