Vlieepoort, also commonly referred to as Vliegepoort, is located in the Crocodile River valley to the west of Thabazimbi. The Crocodile River originates in the Witwatersrand area and flows in a northerly direction, via the Hartbeespoort Dam, until it joins up with the Marico River on the Botswana border. Here it forms the Limpopo, which was popularized by Rudyard Kipling as “the great grey-green greasy Limpopo River” in his short story The Elephant’s Child. Like most other poorts, Vlieepoort is fairly flat and has a height gain of just 42 metres, but it is much longer than the national average at over 12 kms. The road surface is gravel, but it is generally in a good condition and can be driven in any vehicle, weather dependant.

This tough gravel road pass is located entirely within the Grootwater Nature Reserve near Lephalale (formerly Ellisras) in the Limpopo Province, but it is a public road and no restrictions have been applied. It is very long (18 kilometres) and difficult, and could take between 45 and 90 minutes to traverse, depending on your vehicle and your level of experience. It would probably be possible to travel the route in a high-clearance vehicle from east to west, but the opposite direction would require the use of a 4x4. The pass has gained a reputation as a bike killer, and adventure motorcyclists are advised to apply extreme caution and common sense if they attempt this route. Avoid this pass entirely in wet weather.

Passing through the Soutpansberg, Wyllie's Poort (part of the N1 between Louis Trichardt - Makhado and Musina) boasts a rich archeaological, geological and cultural heritage, and is also a bird-watching hotspot! It lays claim to being the second northern-most tarred pass in South Africa and offers attractive scenery with lots of twists and turns over a distance of 3,57 km with a small altitude drop of just 57 vertical metres.
