Why dive here
With 118+ marine species recorded in the area - including dolphins, dwarf minke whales, humpback whales, ocean sunfish (mola mola) and orcas - North Stack offers some of Northumberland & Northeast's richest pinnacle diving.
North Stack gives you a good look at some solid UK reef diving. Expect to find plenty of crabs and lobsters tucked into the crevices, along with some curious wrasse darting about. It’s a site that rewards a slower pace, good for newer UK divers getting comfortable with temperate waters, or anyone who enjoys exploring rock formations up close.
