The horseshoe-shaped Greek island of Milos, which is the southernmost island of the western Cyclades, is a real unsung pearl of the Aegean. Volcanic by origin, the island has a stunning array of landscapes and beaches with backdrops of multicolored cliffs and water that dazzles with crystalline greens and blues. Its captivating geological formations are the result of undersea eruptions that started perhaps up to three million years ago, which piled up layers of lava that reacted to the island’s geothermal waters and created a kaleidoscope of rock formations and sea stacks like the rock of Arkouda that jut up spectacularly from the sea floor in many places along the island’s 126 kilometers of coastline. Look carefully and you can sometimes even see steam rising from fumaroles on both land and sea, and there are abundant mineral springs on the island too. Milos does not have a caldera like nearby Santorini, but it is full of marvels forged by nature, making it a sensory feast unlike any other.
