    CharacterWreck dive

    The Llanishen wreck is one of those Mediterranean dives that just sticks with you. We love a good piece of history, and this Welsh freighter, sunk by a mine in 1917, has definitely earned its stripes. Dropping down onto the deck, you immediately get a sense of its age – the metal is heavily concreted, covered in sponges and red coral. Our favourite part is nosing around the cargo holds; they’re pretty open, letting in shafts of light that reveal schools of cardinal fish darting around. You’ll often spot common octopus tucked into crevices, their eyes watching you, and we’ve had some fantastic encounters with big fork-beards and the occasional dark tonguefish lurking on the sandy seabed nearby. It’s a fantastic dive for anyone who appreciates the character of an old wreck, rather than a perfectly preserved one. The marine life here is the real star, transforming a casualty of war into a living reef. We'd suggest going early to avoid any boat traffic, especially in summer. Keep an eye out for sea scorpions camouflaged on the deck plates – they’re masters of disguise!

    Safety Notes
