There are two Mount Olympuses—and only one you can climb.
In Greek mythology, this is the celestial abode of the Twelve Olympians—a metaphysical realm, not a physical location mortals can reach. Homer describes it as a place of eternal calm, no wind or rain, where gods feast on ambrosia. It exists in story, not geography.
The highest mountain in Greece (2,917 m / 9,570 ft), straddling Thessaly and Macedonia. You absolutely can visit and hike it.
So: mortals can’t reach the mythical Olympus—but the real one offers world-class alpine hiking amid rare flora, chamois, and golden eagles.
