Let’s be honest, you’re not coming to the Scottish West Coast for balmy water temperatures. You’re coming for the adventure, and Tomath delivers. This isn’t a deep dive, peaking at just 1m, which means a lot of what makes it special is accessible to almost everyone, even snorkellers. The Tomath, a sailing vessel that went down in 1870, lies broken up near Orsay Island, her story etched into the seabed. What we really love about this site isn't just the history, it’s the sheer density of life that has taken hold. We’re talking crabs scuttling over rusted plates, anemones carpeting every available surface, and often, small shoals of fish darting in and out of the wreckage. The real draw, though, has to be those two locomotives, once deck cargo, now just ghosts of their former selves. Seeing the outline of a wheel or a boiler under the water, knowing its journey ended here, is quite something. It’s a dive that rewards slow exploration and a keen eye, perfect for photographers or anyone who appreciates a wreck with a proper story to tell. Be prepared for chilly water, but the visibility here can be surprisingly good on a calm day. Our advice? Go at slack tide to really soak it all in without fighting any current.
