Why dive here
SPIO is a wreck dive where divers can encounter dolphins and sea turtles. Water ranges 15-26°C, warmest July, August, September.
SPIO isn't your typical Alonissos dive, given it’s a wreck. This old trawler went down in 1975 after a fire, and she now rests in just 5 metres of water, making it a cracking spot for an extended safety stop or even a snorkel if you’re keen. We often find her bow is still quite intact, with the stern more collapsed, but the sheer size – over 54 metres long – means there’s plenty of structure for groupers and schools of damselfish to hang around. It’s a shallow, easy dive, perfect for photographers or anyone wanting to spend some real time exploring a piece of history. Just be mindful of the "dangerous wreck" classification; we’d suggest keeping a respectful distance from any obviously unstable areas.
