Sure, you can make your way around Islamabad without a rental car. But with loads to check out here, having one would certainly make your stay more enjoyable. If you want to get out of the city and into the great outdoors, opt for a car rental with some power. A full-size or mid-size SUV will get you to the surrounding mangroves in style. Rather spend most of your vacation right in the city? A mini or compact car is a good choice. Maneuvering through narrow lanes and squeezing into tight parking spaces will be a snap in one of these.
