Grab your suitcase, stroll out of Charleroi Airport (CRL-Brussels South Charleroi), and collect your rental car. Which one you jump into depends on where you’re venturing. If you’ll be spending the majority of the time driving in downtown Charleroi, around 3 miles from the terminal, opt for something zippy. A compact car that’s fuel-efficient will be perfect for those busy city streets. But with a wealth of things to see, like the gorgeous caves of the region, there’s a good chance you’ll rack up those miles. A larger vehicle, like a full-size car or an SUV, will make longer road trips more comfortable.
