The turn off to Seweweekspoort is on the R62 between Ladismith (22km) and Calitzdorp (28km), opposite the small settlement of Amalienstein. After turning off on the dirt road, continue for about 10km to get to the poort.
From this point, time will slow down to a trickle, particularly if you have a camera in your hand, as every bend in the road brings a brand new variation on a theme of contorted sandstone. Although it is traditional for photographers to seek out the rich ambers of early morning or late afternoon light, the poort is deep and narrow and many of its cliff faces are swallowed in deep shadow at these times. So, it is best to break this golden rule and photograph the kloof at midday for best results.
The poort is similar to Meiringspoort in structure, but less touristy and makes for a more authentic experience.
