Why dive here
With 118+ marine species recorded in the area - including dolphins, dwarf minke whales, humpback whales, ocean sunfish (mola mola) and orcas - DUNDALK offers some of Northumberland & Northeast's richest wreck diving.
The Dundalk is a serious piece of history, resting upright on the seabed at 50 metres, which makes it a standout for technical divers in the North East. We love diving this wreck when the conditions align, usually on a slack tide on a neap to avoid the worst of the North Sea's push. Dropping down, the first thing you notice is the sheer scale – 71 metres of steamship, remarkably intact for a vessel sunk over a century ago. The twin boilers are a particular highlight, massive iron structures now completely encrusted with plumose anemones, creating a soft, feathery landscape. We've spent many a decompression stop just hovering, watching the current gently sway their tentacles. Look closely and you’ll find the resident crabs and blennies tucked into every crevice. Our favourite spot is the stern, where the twin shafts and propellers are still clearly visible, often attracting inquisitive wolffish patrolling the perimeter. This is a dive for those comfortable with depth and overhead environments, offering a real sense of discovery rather than just observation.
