Cedarberg Kloof (Magaliesberg)

verified Ungraded High flood risk Rustenburg, North West

The steepest kloof in the MCSA-owned Tonquani complex, with the Frog Gully abseil at the bottom end and Help-Help Pool's polished traverse as the technical cruxes.

Distinct from the better-known Western Cape Cederberg (the wilderness area north of Cape Town); this Cedarberg Kloof is in the Magaliesberg near Pretoria/Johannesburg. Access crosses other landowners' property via MCSA-negotiated agreements, and breach risks permanent closure. No bolting and no fires permitted. Muggings have been reported in the surrounding area; the MCSA explicitly advises vigilance. About 1 hr 20 min drive from Pretoria via Buffelspoort Dam.
