HMS HILDASAY - Diani Beach & South Coast

The HMS Hildasay sits in a wonderfully shallow five metres, making it an ideal spot for a long, relaxed dive or even a snorkel if the conditions are calm. This isn't one of those wrecks where you’re just looking at a few scattered ribs; the Hildasay still has a real sense of its former self, a trawler from 1941 that met its end in 1945. We love how the light plays on the remaining structure, picking out the colours of the corals and anemones that have completely taken over. You can spend ages here poking around the superstructure, which is now a bustling mini-reef. We've seen everything from lionfish tucked into shadowed corners, their fins fanned out, to busy schools of snapper darting in and out of the old deck plating. It’s perfect for photographers wanting to capture both the historical feel of the wreck and the lively macro life. Visibility here can sometimes be a bit variable, especially after heavy rains, but on a good day, with the sun high, it’s a brilliant, easy dive that truly shows how quickly the ocean reclaims its own.
