Spend a half- or full-day blasting through San Antonio Bay on a Jet Ski. After a safety briefing, hop aboard the Jet Ski and ride out to sea. Cruise by sweeps of sugary golden sands as you zoom around the crystal waters. Venture out to the tiny laid-back island of Formentera to admire its coves and beaches, and look out for dolphins swimming in your wake. Ride solo or take a passenger along for the ride.
