The Legendary Caves of Hercules | All You Need to Know Before You Embark on a Mythical Day Trip from Tangier, Morocco

During the tenth labor of Hercules, which was to retrieve the cattle of Geryon, a fearsome giant, he had to pass through the Atlas Mountains, then thought to be the edge of the known world. Legend has it that instead of scaling the mighty mountain range, Hercules smashed through it with his superhuman strength, creating the Strait of Gibraltar and separating Europe from Africa. The Caves of Hercules are said to be the place where he rested after this heroic act before moving on towards his eleventh labor, i.e., stealing the Apples of the Hesperides.
