Naroegaspoort is a gentle drive with easy gradients synonymous with typical poort statistics. It includes two crossings of the Plessisrivier, which is usually a bone dry river bed. These crossings mark the start and end points of the poort. There are only two wide corners and the rest of the poort is a straight-line drive through the rugged poort, which forms a passage through the east-west axis Grootrivierberge about 50 km east of Willowmore in the Karoo. The poort squeezes the road and the railway line into its confines and both parallel each other for most of the distance through the poort. This is an arid, water-scarce part of South Africa, where much of the vegetation consists of succulents.
