Walter Sisulu National Botanical Garden – Geological Trail Hike

A stranger let us look through his scope, pointed up at a cliff face where two of Roodepoort’s most-watched residents were building a new home. Mahlori and Makatsa — black eagles, paired for life, minor celebrities to anyone who’s spent time at Walter Sisulu — had lost their last clutch back in May. Whatever went wrong, they weren’t dwelling on it. From where we stood on the lawn, all we could see was rock and sky. Through the scope, we could see the future.

It was a 40-minute run up the N14 towards Krugersdorp, left home at 06:15 to collect a fellow hiker on the way, and a stop for a fancy coffee somewhere in the middle because that’s non-negotiable on a Saturday. Walter Sisulu National Botanical Garden sits in Roodepoort, not far from Kloofendal, where we’d done the star gazing thing the weekend before — starting to feel like this side of Joburg owes us rent.

We rolled in just after 07:30 to find the gates open but useless without a ticket. Turns out if you’ve booked online, you get into the parking area from 06:00. If you haven’t, you’re standing around until 08:00. We hadn’t. A quick scramble on our phones fixed that.

18 of us in total, under a clear morning. 11 were up for the Geological Trail, which I was leading. The rest peeled off with another hike leader to explore the lower gardens at a gentler pace. We waited for stragglers until 08:30, did the registration and group photo shuffle, and finally got moving.

Early on, word came through: the Geological Trail doesn’t loop right now — construction has cut the usual circuit — so it’s out and back, and the recommendation is to walk it anticlockwise, which stretches the route out a bit longer. Fine by us.

The climb starts almost immediately. Loose red dirt, embedded rock, the odd set of log-and-stone steps cut into the slope, and grass gone gold with winter on either side. Going up isn’t a drain on energy this morning, judging by the chatter drifting up from behind me — nobody else seems to feel it either.

Scattered along the way, plaques did the talking instead. The Geological Trail isn’t named for nothing — it’s built around a sequence of rock specimens laid out more or less in the order they formed, some going back over 3 billion years. One plaque broke down how debris slides and rockfalls carve up a hillside like this one — the kind of thing you stop to read once, then start noticing everywhere for the rest of the hike.

We came down off the trail, through a narrow corridor of the garden, and the lawn opens up in front of us. To the right, across that stretch of grass, Witpoortjie Falls sits in the distance — dropping in stages down a cliff face of orange and rust-red rock, water splitting and rejoining itself over a few tiers before settling into a pool at the base.

We cross the lawn to the barrier at the foot of the falls and take a few photos there — the group shot, the opportunity calls for it, this is probably the most beautiful part of the garden, then a few solo ones with just the falls and the rock behind us.

Nothing about this hike was hard, exactly. It’s more that the Geological Trail draws a clear line — the climb has some bite to it, and if a comfortable stroll through the garden is what you’re after, this isn’t it. Stick to the lower parts of the garden instead and let the Geological Trail be for another day.

For everyone else, it’s an easy recommendation. Nothing here felt overrated — the falls earn the hype, the climb earns its name.

I’d go back, ideally once the construction wraps up and the trail runs as a full loop again rather than out and back. Nothing I’d change about the morning itself, though. A few of us stuck around after for a cold one and something to eat, and that was as good a way as any to close out a good morning in the garden.

Paying at the venue turned into its own small saga — some technical hiccup with the card machines that took a while to sort out — but eventually food and drinks were settled and we made our way back to the parking lot. Hiking boots came off, comfortable shoes went on, goodbyes were said, and something cold was grabbed for the road. Then it was back through Roodepoort, onto the N14, and down to Pretoria.

Just a good morning in a garden that punches well above its name.

Currently an out-and-back route rather than a loop, due to construction on the upper section; recommended direction is anticlockwise. Interpretive plaques along the way cover the geology of the area. The trail ends at Witpoortjie Falls, the garden’s centrepiece.

Good to Know
