Bosua Pass is a high mountain pass at an elevation of 1,728m (5,669 ft) above the sea level, located in central Namibia. The pass is traversed by the C28 road.
The road over the pass, also known as Boshua Pass, is one of the Namibia's steepest routes, reaching a gradient of 1:5 or 20% slope as it descends onto the Namib plains.
The road is gravel an tarred and is not suitable for trailers or caravans. There are some very steep sections as you drive over the mountain and as such you should not try to do it with a car that does not have decent tires and brakes.
