Milos
Greece · Mediterranean
Milos is a volcanic Cyclades island renowned for its dramatic underwater geology — sea caves carved by wave and heat, basalt columns, and thermal vents that hint at the island's fiery origins. The marine environment is rich with posidonia meadows, colourful sponges, and a surprising abundance of cephalopods and reef fish.
