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) - SILVONIA offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The Silvonia, a steamship that sank back in 1935, now rests in the shallows off the Cornish coast, making it a cracking dive for a calm day. At just six metres deep, it’s a brilliant site for newer divers or those looking for an extended bottom time without needing advanced certs. The wreck itself is a bit broken up but still recognisable, with parts of the hull and superstructure home to plenty of wrasse and blennies darting between the metalwork. We've seen some decent lobsters tucked into crevices here, too. It’s a proper piece of local history, easy to get to, and a good reminder that even shallow wrecks have stories.
