Whether or not you're into cars, you won't regret checking out the over-the-top automobile collection of Sheikh Hamad bin Hamdan al-Nahayan—a royal-family member fondly called the Rainbow Sheikh. True to his nickname, he has assembled Mercedes vehicles in every color of the rainbow here. The space is also home to 200 different kinds of cars, from off-road machines to American classics—and even the world's largest truck. This fascinating study in extravagance is a great place to stop on the way to or from Liwa. To prepare for a trip, watch the "Mercedes Rainbow" episode of the BBC show Top Gear.
About 45 kilometers (28 miles) south of Abu Dhabi, you’ll find this museum, home to the car collection of the “Rainbow Sheikh,” Sheikh Hamad bin Hamdan Al Nahyan. He’s built a huge garage in the middle of the desert to house his collection, which includes the world’s largest truck and an RV in the shape of a globe, not to mention an entire rainbow of Mercedes sedans, one for every day of the week.
