Kleinrivier means "Small River" in Afrikaans and is named after the Klein River in the area that mouths out near Hermanus where the range begins in the west, then continues eastward to north-east of Stanford and terminates at Akkedisberg Pass.
[1] The highest mountain in the range is Maanskynkop (964m) (Afrikaans: Moonshine Peak) and dominates the entire Walker Bay coastline.
The mountains experience a very mild Mediterranean climate, moderated by cool, moist winds blowing off the South Atlantic Ocean.
Although no peaks exceed 1000m, the range is still quite imposing, as it rises very steeply from sea level.
They are more clearly visible south of Caledon and are traversed by Shaw's Mountain Pass of the R320.
