Why dive here
With 176+ marine species recorded in the area - including blue sharks, dolphins, dwarf minke whales, humpback whales and ocean sunfish (mola mola) - HEIDRUN offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The Heidrun is one of those wrecks that just delivers. Not too deep at 30 metres, so you get decent bottom time, and usually, the visibility holds pretty well here. We love dropping down onto her, seeing the stern section first, then finning along the intact deck towards the boilers. They’re a classic sight, standing proud and covered in plumose anemones – pure white in the torch beam, swaying gently in the subtle surge. It’s an older steamship, built in 1871, carrying anthracite when she went down in 1918. That age means the structure is well-colonised. Expect to find conger eels tucked into every dark crevice and schools of pollock circling above the main hull. Our favourite part is exploring the holds; they’re quite open and you can safely penetrate a little way, feeling the weight of history around you. For divers who appreciate characterful older wrecks and aren't afraid of a bit of chill, the Heidrun is a fantastic dive, offering a real sense of exploration.
