Grootrivier Poort (P0397 / R332) - Baviaanskloof

The Grootrivier Poort on the R332, was one of the last passes to be built by South Africa's most famous road engineer, Thomas Bain. This masterpiece opened up the seemingly impassable 200 km mountain wilderness of the Baviaanskloof between Willowmore and Patensie.

The poort only has 16 bends,corners and curves with a very mild descent gradient that appears to be flat when driving it. The topography is magnificent as the river and the road follow each other faithfully through the towering cliffs of the poort amongst dense riverine vegetation. The road is generally quite good throught his section and most people drive too fast, which means you see less. Expect to see a range of animals, like kudu, reedbuck, baboons and monkeys - and more so if you drive through early in the morning. As the road was carved out of the mountainsides, it left an open display of the various rock formations, which range from solid Table Mountain sandstone to the unusual pebble conglomerate.

Of the 7 passes and poorts in the Baviaanskloof, there are five which are proper passes and two which are poorts. These are Studtis Poort and the Grootrivierpoort. Poorts are different to passes in that they generally have very easy gradients as they follow the course of a river through a mountain range. They are also notoriously prone to flooding and Thomas Bain famously recorded in his journal: "There are three major headaches for road builders. They are water, water and water". Bain had a singular dislike for building roads through poorts and ironically, whilst he was building the extraordinary Swartberg Pass, the nearby Meiringspoort all but washed away in a devastating flood. Bain was subsequently called in to realign the road at a higher point than the flood level.
