Jonkershoek Nature Reserve

Jonkershoek is a horseshoe valley closed at the head by high peaks, with the Eerste River running out of it towards Stellenbosch. A one-way circular road of about ten kilometres loops through the valley floor - drivable, cyclable or walkable - and hiking paths climb from it: the Panorama route around the rim, and shorter walks to waterfalls in the side kloofs. The valley has a scientific history that outlasts most reserves: catchment experiments started here in the 1930s measured how pine plantations affect streamflow, and the results shaped water policy across the country. Those pines have largely been removed to let fynbos return. The mountains are steep enough that the valley is in shadow early, and after the 2015 and 2019 fires the slopes carry visible bands of regrowth. Daily entry is capped and weekends book out.

History

The name is said to come from Jan Andriessen, a bachelor midshipman known as Jan de Jonkheer, who received one of the freeholds Simon van der Stel granted in the valley in the 17th century and called his land Vallei Jonkershoek. The Assegaaibosch farmstead dates from 1790; in 1817 Lord Charles Somerset granted the land to Wouter Eduard Wium on condition that he plant oaks, and many huge oaks still stand. In 1960 the Cape Provincial Administration bought Assegaaibosch and restored the house, now a national monument used as a guesthouse, and the reserve also holds several kramats, among them that of Sheikh Sayed Ahmad Singosari Al-Shattari (Wikipedia, Jonkershoek Nature Reserve).

What you'll find

• The circular road - a one-way ten-kilometre loop through the valley floor.
• The catchment experiments - 1930s research plots that changed national water policy.
• The waterfall walks - short climbs into side kloofs off the loop.
• The fire regrowth - fynbos returning where pine plantations were removed.

When to go

September to November for flowers; autumn for clear air. Half a day. Book ahead - daily numbers are capped.

Before you go

Entry is capped and weekend slots go early. Gate hours are enforced and cars get locked in. Paths above the valley are steep with no shade. Sections close after fires and in high fire danger. Popular with trail runners and cyclists, so the loop road is busy.
