Well that depends on where you plan to wander. Downtown Ciudad Guayana, about 9 miles from Puerto Ordaz Airport (PZO-Manuel Carlos Piar Guayana), can be challenging to drive in. Make it easy on yourself by going for something compact, fuel-efficient, and simple to operate. Bear in mind that Ciudad Guayana is also the gateway to some of the coral reefs in Caroni. If your trip is more about steering down lengthy stretches of road, then you may prefer something with a little more comfort and room to move around. How about an SUV or a full-size car?
