After something that won't cost a small fortune? Consider an economy car. This small vehicle is the most popular type of rental car in French Guiana (and just the thing if you're on a tight budget). Fill up the tank for less and you'll be zooming around cities like Matoury and Kourou in no time.It's always a good idea to take a break from the city, and if you do, you'll be handsomely rewarded. With sandy shores, rolling hills, and mountains to marvel at, French Guiana is ripe for exciting adventures. A bigger vehicle like a four-wheel drive or an SUV will give you and the crew more room for those scenic drives.
