005 – Bottelary – (4km / 230m Elev)

Botterlary is one of those “mountains” that is used extensively as a commercial RF high-site. It was my first time up here and because I’m a  huge nerd it was interesting to see how it was all laid out, but predictably it is not a great location for sensitive radio experimentation.

Pretty walk up the hill

I met up with a few friends at Koopmanskloof Winery (who had kindly given us permission for the day). We drove Brian’s Landy a few hundred meters up the hill until we reached a boom across the road and parked out of the way. We then trekked the rest of the 2km up to the top of the hill. You should eat breakfast before you do these kinds of things. I of course hadn’t eaten breakfast and felt like dying a few times on the way up. It’s an unforgiving slog.

There’s probably 50 of these towers

It is however still a pretty walk, and once you reach the top you’re surrounded by antennas and small buildings humming away ominously.

We set up in the shade of one of the small buildings and I did actually manage to make contact with one person who was only a few km away. There was an S9+ noise floor, which for non-radio people basically means so much interference that any signal that wasn’t absolutely booming in would not be heard over the noise.

Original location

I made the executive decision that we should move downhill, away from the towers and set up again to see how thing fared a short distance away.

The new location with all the trappings of civilisation

The new location was much better noise wise; down to S3 and we immediately started making contacts with people all over the country.  The surroundings were a bit spartan though, and a recent fire had made it even more so. My lack of breakfast continued to diminish my enthusiasm and we packed up as soon as we’d made enough contacts to consider the SOTA summit activated.


Overall a fun outing, but there’s definitely other hikes to do before this one.

004 – Dutoitskloof One (MicroMission) <1km

I am really only including this as a blog post so that I can highlight how great a location this is for radio amateurs who want to test their setup in the great outdoors without committing to a crazy hike. From where you park your car to a large, relatively flat open space, is a 300m walk uphill. Just enough to get your heart pumping but still close enough that you might carry something stupid like a table or camping chairs. (I did neither)

What is great about these micro-missions is that they give you an opportunity to look around and think about what might be a great hike, what mountains are around you etc.

For the non-radio-nerd readers, check out hike number 006 where we return to these mountains but climbing up to the top for amazing views.

Soon I will come for you too.


Date: 9 December 2018
Distance and Elevation: <1km and 30m Elevation Gain.
Coordinates: Parking spot -33.696682, 19.074776  Setup Spot: -33.697215, 19.073074
Conditions: Cool with a fresh breeze bordering on “windy” earlier on, but then later hot and very calm.
Radio Stuff: You’ll need a self supporting mast as there are no trees. While technically you’ve got mountains on most sides, you still have great elevation which should give you some great takeoff North and South. There are big power lines running through the valley to the east, but I didn’t pick up any noise.
Notes: The parking spot is quite exposed but with lots of traffic I think it’s pretty safe.

003 – Gantouw Pass (6km / 150m Elev)

This is one of those truly magic hikes that inspire you to keep exploring because you never know what’s just around the corner.


I am fascinated by this part of the mountain. There is a train line that most people don’t know exists, you can touch wagon wheel tracks carved into the rocks hundreds of years ago by the voortrekkers, there’s a canon that was used to notify people when someone had made it to the top, and last but not least, there’s a creepy old train tunnel that runs directly under the N2 at the top of Sir Lowry’s pass for the train you didn’t know about.

Looking back

If I had another lifetime I would spend it documenting the incredibly fascinating micro-history of South Africa. The past of seeming insignificance gives history its texture. Knowing these little stories lets you find wonder in the smallest things. A groove cut into a rock can represent the beginning of an epic journey, a new life in a far away land.

Stumbled across this. Didn’t even open it.

Quick history lesson courtesy of Wikipedia

Gantouw in the Khoi language means eland and historically these large animals crossed the Hottentots Holland mountains at this narrow and steep pass. The Khoi and San people followed the eland and, after European settlement at the Cape, the pass became an important gateway to the Overberg for transport wagons hauled by teams of 24 oxen.

The earliest recorded crossing of the pass was by a Dutch East India Company surveyor, Hendrik Lacus in 1662. By 1821 more than 4 500 wagons were using the Gantouw Pass (Hottentots-Hollands Kloof) each year.

Starting in 1828, a new pass was constructed on the current route that would allow ox wagons to navigate the pass without difficulty. Construction began at a site about 2 km to the south of the Hottentots Holland Kloof, by the engineer Charles Michell using convict labour. The new pass was opened on 6 July 1830, and named after Lowry Cole, the Governor of the Cape Colony at the time.

In 1903 the route was upgraded again when a privately owned railway company built a railway line alongside the road with a level crossing (ie. train/car intersection) right at the top. This is another fascinating part of South African history. The rail industry was a bit like the current private space industry. A few mega wealthy individuals spending fortunes prospecting on which routes, technology and methodology would succeed. That’s a story for another time, but the battles left some interesting remnants, including a “train to nowhere” that I’ll write about another time.

I bless the raaaaains…

Lets get back to the hike. Drive to the top of Sir Lowry’s pass and hook a right into the lookout point. Don’t leave valuables in your car. Take your bags and hop over the N2 to a small awkward section of tarred road that goes nowhere. The tar quickly becomes gravel and you’ll reach a fork.

Side Mission: The right (southern) route takes you down the hill and then runs parallel to the train track. When you’ve walked about 700m you’ll find a small path that leads to railway line. If you follow the railway line back towards the summit (600m) you’ll reach the southern entrance to the tunnel. The tunnel is roughly 250m long and the train line is still used! albeit very infrequently – Don’t be an idiot.

See, I’m not lying the train does still run.

At the fork, take the left (northern) option. It’s a great walk that’s relatively flat and can be quite magical in the early hours of the morning. Around 1.7km in you’ll reach a small path to your left. From here you can see into the small valley that is the top of the Gantouw Pass. We’ll take this left route up for now as it gives us some altitude. I didn’t climb all the way up as I wanted a slightly more sheltered spot to set up in. I walked uphill about 350m and found my spot, but at this point you should really explore. It’s all quite spectacular.

Why I chose not to climb to the top.

I spent a few hours playing radio and exploring, then when I was done I headed back down to the original path and continued on a few hundred meters to the signage. Turning left (north-west) takes you into the Gantouw Pass. You only need to walk a few hundred meters before you start to notice the grooves cut into the rocks from the ox wagons. I encourage you to keep walking down the pass. The further you go the more you’ll appreciate the magnitude of getting ox wagons up that mountain.



Finally on my way back I hopped up the hill to the old signal canons. These canons were used for a few different things, but usually to announce that someone (often a trader) was coming. I’m guessing these were only ever fired at certain times of day so that people (in Strand etc) would know when to look up.

Once you start exploring these mountains you’ll realise that there are so many nooks and crannies to investigate. Starting from the same parking spot you could also embark on the 22km hike (with >1000m elevation gain) up to Hansekop, or go and look at this big hole (probably trespassing). The Hottentots Holland mountain range is massive and full of adventure. This little hike was the first hit that left me wanting more.

Conditions: Cool, overcast with a little bit of drizzle.
Radio Stuff: You’ll need a self supporting mast as there are pretty much no tall trees. The summit would provide a better take-off angle if weather permits. Had great contacts all over the country.
Notes: Leaving my car at the parking lot in the early hours of the morning was sketchy as frig. I wonder whether you could get an Uber from Gordon’s bay?

002 – Gordon’s Bay Madness (2km / 200m Elev)

This was a bit of a white whale. I had set out early to find some way to access the mountains around Steenbras Dam. From Google Earth you can see all kinds of interesting roads and paths, but when you try and get anywhere near there you’re met with locked gates and razor wire. I then drove the winding road technically called “Steenbras Dam Mountain Pass” on the Gordon’s Bay side up to the official Steenbras Dam waterworks / lookout point thing. At the top the security guards very nicely told me that no public access has been allowed for the last 10 years. I should probably have tried to send some emails ahead of time and gotten permission.


I decided that the next best thing was to get up onto the mountainside from the edge of the Gordon’s Bay housing line. After driving around a while I found what looked like the start of a hiking path.


Tthe Danie Miller “Hiking Trail” is really just a very short contour path that skirts around the back of the houses. I’m sure it’s probably lovely, but not the kind of thing I’m into, although I should probably do it some day.

Halfway up, looking up.

Because I’m stubborn and just a little bit stupid, I decided to hike up the very steep fire break to see where it took me. It is steep as hell, but you’ve just got to keep putting one foot in front of the other and eventually you get to the top.

On the top left you can see a little buttress sticking out of the mountainside. I decided that’s where I wanted to go… mainly because it was somewhere to string my dipole antenna across because this kind of terrain has zero tall trees.

Halfway up, looking back down.

This is where things get a bit hairy. At the top of the firebreak you’ll find the lower pumping station, and that means water. With no actual paths I climbed up a slippery “crevasse” dripping with water and rocks that fell apart when you touch them. This was stupid, I was alone.

At the top I got my antenna setup and soon started to get sunburnt. I set up a little impromptu shade cloth with an old sheet that I carry in my bag. The pink thing in the below photo is a single bed sheet which should give you some sense of scale. It is really pretty up there but I had to keep one leg dug into a rock to keep myself from slipping off the edge.

Playing house.
My little home for a few hours.

Coming back down was way worse. I was hot, had run out of water, and was rushing to try and avoid getting more sunburnt. If you do this route, do not try and cut corners up or down. You need to bundu bash the long way around the back. I (obviously) took a short cut and had a bit of a moment (ie. mild panic attack) on a rock face where I couldn’t figure out how to move up or down.

The lower pumping station, or whatever it is.
Looking down from the top, it really doesn’t seem that high.

I am not too proud to admit that I had a little moment when I got back down to the stream. It was the coldest, most welcoming water I have ever tasted. I sat there for an awkwardly long time dousing myself in fresh bottles of water.

Distance and Elevation
: <2km  and 200m Elevation Gain.
Coordinates: Parking spot -34.169608, 18.851161   Buttress: -34.173199, 18.852497
Conditions: Super hot, 40 degrees with very little wind so needed shade. No actual paths.
Radio Stuff: It’s relatively easy to string up a 20m dipole across the gap, but obviously it’s a very compromised setup with rocks pretty much surrounding you. I was able to make SSB contacts all across the country and this was the first time I tested JS8Call portable and made contact with stations in JHB. There is the occasional burp of very strong RF noise that I suspect is a pump spinning up at the waterworks).
Notes: This is a very remote location. No one will hear your screams.

001 – Behind Rhodes Memorial (MicroMission < 1km)

This was really a quick excursion to test my radio kit, but it has a nice steep uphill to the trees which gets the heart pumping for a few minutes.




Park at the back left-hand corner of the Rhodes Memorial parking lot and start walking up the obvious path that winds slightly to the left. You’ll cross over a contour path (not *the* contour path obviously) but just keep on ascending until you reach some tall pine trees with the right kind of distances between them (if you’re doing radio stuff). I bundu-bashed off the trail about 100m so that no one would see me once I was set up, but I did get some very strange looks from other hikers while I was trying to get the damned throw lines up.

Coordinates: Parking spot -33.952742, 18.458279   Tall Trees: -33.953195, 18.455623
Conditions: Perfect (needed shade)
Radio Stuff: Huge pine trees and my throw line meant I was able to get a 20m dipole up high (easily 15m AGL) and had surprisingly good communications despite being down the side of a mountain. Chatted with a friend in Johannesburg and Namibia (SSB) for quite a while and got the power down to 25w while still able to hold the conversation. Very little noise considering my proximity to civilisation.
Notes: There have been a lot of muggings in this area. It is stupid to take expensive kit in a nice bag up here.
