The Jan Muller Pass is a short, steep pass, with a descent and ascent over the Gouritz River via a low level concrete bridge, which is also named after Jan Muller. It's located on the R327 connecting Van Wyksdorp with Herbertsdale.This rugged gravel road pass is fairly short at 3,6 km and descends very steeply down the western side, then ascends in a series of tight switchbacks after crossing the Gouritz River at an altitude of just 68m ASL.
The western ascent is very steep with gradients as steep as 1:5, but the road builders have concrete-stripped this section allowing for good traction. It makes the road driveable in a normal car but due to the rough nature of the concrete surface most vehicles will need to remain in 1st gear if driving the pass in the reverse direction, until western summit is reached.
