    Ah, D1. This is one of those spots in Cornwall and Devon that just *delivers*. We’ve spent a fair few hours down here, and it always feels like uncovering a secret, even if it’s on the map. The geology itself is interesting – we’re talking about a patchwork of rocky reefs, gullies, and small walls, perfect for slow exploration. Drop in on a slack tide, ideally, and drift along. You'll want to take your time here, peering into every crack and crevice. Our favourite thing about D1 is the sheer variety of life tucked into those rocks. Forget the flashier tropical stuff; here it's all about the subtle beauty. We’ve had incredible encounters with thornback skates settled on sandy patches, practically invisible until you’re right on top of them. Keep an eye out for conger eels, too; they love the darker holes. And the smaller stuff, the butterly blennies peeking out, the european fan-worms waving gently, that's what truly makes this site. We often find ourselves just watching a patch of crumb-of-bread sponge for a few minutes, seeing what’s living inside. It’s a great site for macro photographers and patient naturalists alike, offering a genuine taste of temperate diving at its best.
