The countryside outside the major towns is extremely variable, and offers exciting opportunities for motor rallying. This popular sport is highlighted by the internationally supported Safari Rally held throughout the Easter weekend each year. It is a stiff test of skill and endurance, both for the drivers, and vehicles, as the route takes them over desert, swamps, mountainous terrain, bush and grassland, where normally one would attempt to venture only in four-wheel drive vehicles. Besides this great event, almost every weekend throughout the year, races or rallies are organized for motor enthusiasts.
