From the website of Visit Aruba they explain about Franse Pas. Legend has it that French pirates tried to invade Aruba in the early 17th century round harvesting time and were confronted by Indians in this narrow passage above Spanish Lagoon. The Frenchmen were winning the battle and the Indians had to flee and hid in a cave nearby where the Frenchmen could not get to them. The Frenchmen thought it was good to smoke the Indians out of the cave, but instead the Indians got killed by inhaling the smoke. After this encounter, the passage became known as ?Franse Pas? or ?Rooi Frances? in Papiamento, which translates to ?Frenchmen?s Pass? in English. Today inhabitants near "Frenchmen?s pass" claim they hear crying noises from the Indians during the evening. Some say the Indian ghosts are awake and haunting the area known as Spanish Lagoon.
