    The Glen Lyon wreck in Aldabra is pure magic, and frankly, we think it’s one of the most underrated wreck dives out there. She's a British tanker, deliberately scuttled in 1879, and lies so shallow – barely breaking the surface at low tide – you can almost reach out and touch her from a dinghy. We love that it’s technically a snorkel site, but the experience is so much more than that. You’re swimming through history. The hull is still largely intact, a skeletal frame that catches the light beautifully, especially in the late morning when the sun angle is just right. You can fin right through the holds, watching schools of juvenile snapper flit between the rusting beams. Parrotfish scrape at the encrusting corals, their crunching audible even with a mask on. Our favourite part is spotting the octopus that often hides amongst the deeper crevices, its eyes tracking you as you pass. It’s an easy, leisurely fin, perfect for those days when you want something relaxing but still profoundly impactful, and absolutely ideal for photographers looking for unique light and composition.
