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) - Wreck of HMT Arfon offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The Wreck of HMT Arfon holds a special place for us, a tangible piece of history sitting upright at 35 metres. When the visibility is good, which is often surprisingly decent in this part of Cornwall, the trawler comes into view slowly, almost eerily, as you descend. We love drifting along the deck, picking out the details – the impressive 6-pounder gun still mounted on the bow, a solemn reminder of its wartime role. It’s a great dive for divers comfortable with depth, allowing plenty of time to explore the bridge area and the surprisingly intact stern section. The Arfon has become a fantastic artificial reef. We’ve seen conger eels peering out from gaps in the plating, their thick bodies camouflaged against the rust. Lobsters tuck themselves into crevices, and the sheer number of jewel anemones covering almost every surface is incredible, painting the metalwork in a thousand tiny, vibrant colours. Our favourite spot is the stern, where you can often find large schools of pollack circling the structure, their silver scales flashing in the ambient light. It’s a powerful dive, especially knowing its story, and a real standout for UK wreck diving.
