Greece
Volcanic hot springs bubble through the sea floor at a tiny island most itineraries skip.
Warm water rises through the sea floor in patches β volcanic heat seeping up through sand and rock, turning shallow coves into open-air thermal baths; at Agioklima the spring sits right at the waterline. The big itineraries pass the island by, and the Kastro's nested medieval houses stay quiet.
Kimolos gave its name to the Greek word for chalk β kimolia β mined here and exported across the Mediterranean for centuries. The island sits on volcanic geology that produces thermal springs along the northeastern shore, where bathers find warm patches at the sea surface. The medieval kastro at Chorio is an unusually intact double-walled settlement across the Cyclades and has a church at its centre. Kimolos has fewer than 1,000 permanent residents and most visitors arrive by the small shuttle boat from nearby Milos.
Solo
Walking the empty trails between volcanic beaches, soaking in the thermal shallows, and reading in a kastro courtyard where the only sound is wind.
Couple
Finding warm sea patches at sunset, ladenia flatbread at the harbour, and the deep quiet of an island the crowds forget.
Ladenia β the open-faced flatbread of tomato, onion and generous olive oil β is the island's defining dish.
Kalamari comes flash-fried at the port tavernas, eaten with your hands.
