Alright, let's talk Neptunia. Forget those deep, dark Irish wrecks for a minute. This one's an anomaly, a total outlier, and frankly, we love it for being so different. The Neptunia sits practically on the beach, barely tickling the surface at high tide, and completely exposed at low tide. It's a proper giant, 154 metres of steel that ran aground in 1957, and it’s a brilliant scramble. Walk out at low tide and you can actually explore the colossal ribs of the hull, barnacled and rust-stained. We’d suggest bringing tough boots. The light here, filtering through the shallows, gives everything a strange, almost ethereal glow. Look closely in the tidal pools around the wreck's base; you’ll find crabs scuttling and anemones clinging to the metal. It’s not a dive in the traditional sense, but more of a unique intertidal exploration, perfect for those who want to get hands-on with history without the need for a tank. Our favourite way to experience it is to time your visit with a receding tide, giving you maximum time to poke around before the water creeps back in. Just remember to keep an eye on the clock.
