    StandoutExceptional marine biodiversity

    The Denise, near Mullion, is one of those wrecks that really grows on you. It’s a steamship, sunk in 1917, and it sits in a very forgiving 11 metres of water, making it accessible for most divers. We love that you can really take your time here. The wreck itself is quite broken up, but you can still make out the bow and stern sections, and the boiler is a prominent feature that always draws us in. What makes the Denise special, for us, is the sheer volume of life that has moved in. Spend a few minutes motionless near the boiler and the wrasse will come right up to your mask, curious and bold. We’ve seen conger eels poking out of every nook and cranny, and the deck plates are often carpeted with jewel anemones, shimmering with colour even on a greyer day. It's a fantastic site for photography, especially macro, with so many textures and patterns to capture. Our favourite time to dive it is on a slack tide, when the water settles and the visibility can really open up, letting you appreciate the whole site. It’s a classic Cornwall wreck dive, a real character.
