Heron I. Not the big, dramatic, photo-op wreck many divers chase, but she’s got a quiet dignity at 41m. This isn't a dive for the casual Sunday splash. She was a small sloop, caught fire in '95 and burned right to the waterline, eventually settling upright on a sandy seabed. You’ll find her mostly intact, just stripped bare, a stark silhouette against the deeper blue. We love Heron I for its atmosphere. It's a proper deep dive, best done on a calm day with decent visibility. Drop down and you’ll see the low profile of the hull emerging, barnacled and draped in sea squirts. Conger eels often peek from crevices, and the occasional pollock patrols the perimeter. Look closely; her small size makes for intimate exploration, and we’ve found some surprisingly vibrant jewel anemones clinging to the burnt timber. Our favourite spot is the stern, where you can still make out the rudder and propeller, now completely encrusted. She's a thoughtful dive, a little piece of maritime history that feels very personal down there.
