This attractive poort forms the final part of the R61 between Mthatha and Port St. Johns. It is a typical poort following the course of the Umzimvubu River on it's southern bank. Near the western start lies the village of Isinuka after which the poort is named. There is a deep cutting just after the western start as the road slices through the mountain to reach the Umzimubu River Valley.

There are sections of very steep cuttings that tower some 60m above the road, but other than that the road is straight-forward, which is a relative term, as several dangers lurk along this stretch of roadway. Local traffic officers love doing laser speed traps here, where the speed limit jumps several times between 60 and 80 kph. There are also a number of poorly concealed and sharp speed bumps, which require a reduction of speed to 30 kph or lower, Dogs and livestock can appear out of the dense bush without warning and pedestrians tend to wander along the roadway as there is nowhere else for them to walk and of course, last but not least, are the numerous minibus taxis which ply this route and congregate in numbers towards the eastern end of the poort adjacent to the Pondoland Bridge.

The wide and sluggish Umzimvubu River welcomes drivers as it drifts lazily towards the estuary at Port St. Johns' 1st Beach.
