Erme Estuary
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) - ERME ESTUARY offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The Erme Estuary wreck site is a different kind of dive. Forget dramatic walls or colourful reefs, this is about history and discovery. We love how it’s less about a single intact wreck and more about an archaeological treasure hunt. What you're dropping onto here is an assemblage of cannons, some dating back to the 15th century. It feels a bit like diving through a scattered antique shop that sunk centuries ago. You’ll find iron cannons resting on the seabed, encrusted with local life – spider crabs cling to the barrels, and small blennies dart in and out of crevices. Visibility in the estuary can vary quite a bit, so we’d suggest timing your dive for slack water on a neap tide for the clearest conditions, typically around 5-10 metres. The maximum depth is only 9 metres, making it a relaxed rummage for divers who appreciate the story as much as the scenery. It’s a site for those who enjoy slow exploration, where imagination fills in the gaps between the physical remains.
