Things to Do at Blue Caves

Boat tours cost €25 per person ($27 USD) for access to limestone grottoes where millennia of wave action carved cathedral-sized chambers that glow electric blue when morning sunlight penetrates underwater openings. The sea inside reflects off white limestone walls with such intensity your eyes need time to adjust, while the enclosed space amplifies every water drop and boat engine echo into haunting acoustics. Mediterranean water temperatures hover around 22°C in summer, perfect for swimming in the largest cave where the bottom disappears into sapphire darkness beyond snorkel depth. Book morning departures between 9-11 AM when optimal sun angles create the signature azure illumination that photographers chase but smartphone cameras rarely capture accurately. The limestone releases a faint mineral scent that mixes with sea salt and diesel fumes from fishing boats, while swells rock your boat against cave walls with gentle thuds that vibrate through the hull into your feet.
