    The Union Pacific isn’t your typical deep wreck dive; this is a shallow, sun-drenched exploration of history. We’re talking about a former carrier vessel, run aground back in ’71, sitting in just 3 metres of water. It’s less about penetration and more about seeing how time and the sea reclaim steel. What we love here is the light. The sun dapples right through the water onto the wreck, illuminating every barnacle and the small shoals of fish darting in and out of the exposed ribs. You’ll weave around the skeletal remains, spotting nudibranchs clinging to rusted plating and the occasional pufferfish peeking from behind a corroded bulkhead. It’s a very relaxed dive, perfect for those wanting to spend a solid hour just observing the details, maybe even spotting some of the old cargo anchors still fused to the deck. Our favourite time to visit is late morning when the sun is high, really making the water sparkle around the wreck. Just watch out for the occasional fishing line; it's still an active fishing area.
