    CharacterWreck dive

    The Simos Wreck, resting in the Alonissos Marine Park, offers a solid dive for those who appreciate history underwater. We're talking about a relatively intact cargo ship, sitting upright, which always makes for a more dramatic sight than a scattered debris field. You can navigate through its holds and around the superstructure, finding resident groupers tucked into shadowed corners and schools of damselfish flitting over the deck. It’s a rewarding dive, especially on a sunny day when the light penetrates the Mediterranean blue, illuminating the wreck's every detail. We'd say it’s a good choice for advanced open water divers comfortable with deeper wrecks and exploring inside.

    Safety Notes

    Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.
