Standing on the small launch at Elounda, the Aegean ahead is glass and blue, the seabed suddenly revealing the straight edges and blocks of stone that time has sunk just beneath the surface. Guides give a concise PowerPoint on the shore—maps, dates and the city's footprint—before leading groups into waist-deep water to float above fallen columns and streets now grown quiet with algae.

Bring a snug mask
A well-fitted mask prevents leaks and makes it easier to focus on ruins; test the fit before leaving shore.
Use reef-safe sunscreen
Apply mineral-based sunscreen before entering the water to protect marine life and reduce glare on the surface.
Listen to the guide’s route
Guides mark safer passages and shallow features—follow instructions to avoid damaging ruins or entering deeper channels.
Wear a thin wetsuit in spring/fall
Water can feel cold despite warm air; a 3mm shorty or full suit improves comfort and floatation.
Mask, snorkel and fins
A reliable set improves sightlines and reduces fatigue while you study submerged ruins.
3mm wetsuit (or shorty)
