HMS Amphion
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) - HMS Amphion offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The HMS Amphion wreck is a properly solid dive, a real piece of history lying off the Cornish coast. We’ve always found these old scout cruisers fascinating, and this one, a casualty of the very first days of WWI, tells a story. Dropping down, you're not just seeing metal; you’re seeing the skeletal remains of a ship that met its end barely a month into the war, sunk by a mine. The structure itself is well broken up, but you can still pick out the bow section and some of the machinery, all heavily encrusted now. What we really love here are the sheer numbers of conger eels; they’re everywhere, peeking out from every crevice. You’ll also find lobsters tucked into the plates and schools of pollack hanging above the main wreckage. It’s a dive that suits those with a real appreciation for naval history and a comfort with deeper UK conditions. Dive it on a calm day with good visibility, ideally around slack tide, and you’ll get the best out of it. We always feel a bit of a chill when we think about what happened here; it’s a sombre but incredibly rewarding dive.
