    The *Ismini* isn't a deep dive, not even close. We're talking a foot of water, maybe two on a high tide, yet it’s one of our favourite spots in the Cousteau Reserve for something completely different. This old steamer, built in '29, ran aground in '65 and eventually caught fire, leaving its bones scattered across the reef crest. You’re not diving it so much as snorkelling or, frankly, just wading. But don’t let that fool you into thinking it's boring. We love how the water laps over the rusty plates, creating this rhythmic, metallic whisper. Look closely and you'll see crabs scuttling in the shadows of the hull plates, tiny blennies peeking out of crevices, and juvenile parrotfish nibbling at the algae-covered metal. It’s a photographer’s dream, especially with a wide-angle lens, capturing the wreck’s stark outline against the sky. We'd suggest going at low tide, when more of the structure is exposed and the light really plays off the shallow water. It’s a fantastic spot for history buffs or anyone who appreciates how nature reclaims even the most substantial man-made objects.
