    The Porta Allegra, a 19th-century steamship, sank after a collision off North Carolina, and honestly, we think it’s one of the best wreck dives in the area if you like history you can actually touch. It’s a proper wooden steamship wreck, not some modern metal hulk. What we love about it is how the wood has held up over the decades, sections of the hull still intact, and you can really get a sense of its original form, especially the bow. You’ll weave through the timbers, past the boilers, which are now completely encrusted. It’s the sheer density of growth that really grabs you, a whole ecosystem thriving on the old wood. Expect to see big schools of baitfish shimmering around the deeper sections, and we often spot nurse sharks tucked away in the more sheltered nooks. For photographers, the way the light filters through the structure, illuminating those dense coral patches, is our favourite. We’d suggest going on a slack tide day, the currents here can pick up, making it a much more enjoyable swim through the wreck. It’s perfect for divers who appreciate a wreck with character, not just a pile of metal, and who love seeing how nature reclaims man-made structures.
