ORIENTAL ARGOSY - Lake Atitlan
Forget everything you think you know about wreck diving. The Oriental Argosy isn't some deep-sea ghost. It’s a shipwreck in Lake Atitlan, a freshwater lake high in the Guatemalan mountains. This isn't about pelagics or vibrant corals. This is about history, about a vast vessel that somehow ended up in a lake, and the unique world it’s created. We love the sheer oddity of it. Imagine, a 159-meter steamship, built in Japan in 1957, now lying at a maximum depth of 5 meters. You can literally snorkel over the whole thing. Our favourite part is how the local freshwater ecosystem has embraced it. We’ve seen small schools of fish darting in and out of the superstructure, and the hull is covered in a fine layer of algae, giving it an otherworldly green glow in the filtered lake light. For a unique perspective, we’d suggest going early in the morning. The lake is often calmer then, and the light penetrates better through the surface. Don't expect crystal-clear ocean visibility; it’s a lake, after all. But that slight murkiness actually adds to the atmosphere, making the wreck feel even more mysterious. It’s perfect for photographers looking for something truly different, or anyone who appreciates a story with their dive. It’s not a challenging dive, just an unusual one, and that’s precisely why we rate it so highly.
