PASSA - Alonissos Marine Park
Passa offers a different kind of wreck dive, shallow and easily accessible, which we always appreciate. It's a sailing vessel, sunk at just 3 metres, making it perfect for an extended snorkel or a long, easy dive for any certification level. We like exploring the broken timbers, seeing how the wood has softened over time, and watching the small fish dart in and out of the crevices. Look for octopus tucked away during the day, and sometimes a nudibranch or two on the remaining structure. It’s a gentle site, good for photographers keen on details or just unwinding underwater.
