    The Alex G, a 61-meter carrier vessel, has been resting in the shallows of Alonissos Marine Park since 1983. We love a good shipwreck that doesn’t demand deep air, and this one, at a max depth of just 9 meters, is perfect for a relaxed dive. Built in 1959, her bow and stern are pretty broken up, but the midsection still offers some decent penetration for those comfortable ducking inside. We usually find schools of glasseye fish hovering in the darker sections, their big eyes reflecting our torch beams. Out on the deck, you’ll spot nudibranchs grazing on the algae, and octopuses are often lurking in crevices, their eyes watching you curiously. It’s a site that feels alive, not just a static piece of history. The visibility here is often fantastic, letting the Mediterranean sun stream down and illuminate the entire wreck in a hazy blue. We’d suggest going early in the morning to avoid any boat traffic if you’re planning a surface interval nearby. It's a great spot for newer wreck divers or anyone who just wants to enjoy a long, easy dive exploring a piece of maritime history.

    Cause

    grounding

    The M/V Alex G was a British-built carrier vessel with a long career that began in 1959. By the early 1980s, she was operating in Greek waters under the ownership of Athos Maritime Shipping. Her final voyage began on December 1, 1983, as she steamed from Piraeus, bound for the island of Milos. Her journey was cut short when she ran aground, succumbing to the sea and sinking into the clear waters of what is now the Alonissos Marine Park.

    Unlike wrecks with more violent ends, the Alex G settled peacefully and now rests in just 9 meters of water, making it a spectacular and accessible dive for all levels. The shallow depth allows for long, relaxed bottom times and floods the wreck with natural light, delighting underwater photographers. Divers can easily explore the ship's structure, which has become a thriving artificial reef, teeming with the vibrant marine life protected by the park.
