Take a 23 km drive along the rim of South Africa's most spectacular canyon - The Blyderivierspoort or nowadays known as the Molatse Canyon - and marvel at the scenic wonders the poort has on offer - like the Three Rondavels, God's Window, the Pinnacle and Bourke's Luck Potholes. The road (R532) connects the northern towns accessible from the R36 (Hoedspruit, Burgersfort and Orighstad) with the southern towns of Graskop and Sabie. There is a significant altitude gain of 480 vertical metres, but due to the length of the pass, the average gradient is a mild 1:47. The steepest gradient you will experience is on the eastern sector, where it gets to 1:10.
This is an unusual pass/poort in many respects. Firstly it does not in any way resemble the normal pattern of a road through a poort, where the incising river is always in close proximity. In this case the road follows to the southern rim of the canyon and for most of the drive the true beauty of the canyon remains unseen. Therefore it's important to stop wherever you can and explore the views on foot.
Secondly the vertical profle is much more of a pass than a poort with a large altitude gain, but there are 5 separate summit points, progressively getting higher from west to east. The road has 44 bends, corners and curves of which 6 exceed 90 degrees radius, but none of them are significantly sharp. If you follow the speed limits, it should be a perfectly safe drive. Be aware that this is a densely populated area, so you have the erratic behaviour of local drivers (some fast, some very slow), as well as tourist traffic, which can be equally erratic. There is also the chance of finding livestock on the road and mountain mists with the associated reduced visibility is also common along this road.
