Severnside Sub-Aqua Club - Cornwall & Devon

The Severnside Sub-Aqua Club site, somewhere on the coast of Cornwall & Devon, is a bit of a local mystery in terms of specific dive details. What we do know from the limited records is that it’s got a consistent showing of coastal inhabitants. We’re talking your reliable mussels and periwinkles, plenty of wrack along the shoreline, and the occasional eel poking its head out. You’ll definitely hear the gulls overhead, with both Herring and Lesser Black-backed gulls making their presence known. For divers who enjoy exploring the nooks and crannies of temperate UK shorelines, identifying common species, and maybe even spotting a harbour porpoise if you’re lucky, this could be a perfectly pleasant afternoon dive. It's likely a site best suited for local club members or those keen on a relaxed, exploratory shore entry.
