Bikeways along the water. Paddleboarding under minarets. Evening strolls on Marina Island. Other off-the-beaten-path highlights take you to the Abu Dhabi Falcon Hospital or on a kayaking trip in Mangrove National Park. Of course, you can't miss the awe-inspiring Sheikh Zayed Grand Mosque, or a classic lunch of shawarma, or a ride on a camel through the emirate's desert dunes.
