Visit Saudi Arabia on the Arabian Gulf and you just have to explore Al Khobar, its bustling heart. It flips the script on traditional city status, flaunting everything from a glittering skyline to a sandy coastline. Its big waterfront promenade, the Khobar Corniche, is your go-to for strolls – you can see the ornate Water Tower, overlooking the shore from its own man-made island. If you want to take a dip – you'll definitely be tempted – then Half Moon Beach is the place to be. Its shallow, calm waters have a high salt content, making for effortless floating. Other top attractions include the Sultan Bin Abdulaziz Science & Technology Center (SciTech), with an aquarium, interactive displays and an IMAX theatre. Plus, don't miss the Aramco Exhibit – a museum which delves into the country's fascinating oil industry.
