So I climbed it, couldn't see anything though!
The 14km drive to the south african border post at the bottom of the pass was testing enough for my little hire car, and from there the road is 4x4 only (until it gets tarmaced!), so I had to walk. Easy enough, reached the top in under two hours and got stamped both in and out of Lesotho at the same time.
Visibility was about 50 metres at this point, so it was compass out to head across the trackless moorland plateau towards Hodgsons Peaks, which stand either side of a gently curved pass, known as the Giant's Cup.
Long story short, weather got worse, had to use the GPS on my phone to navigate, but reached both peaks (3250m) and got back to the border post by 2pm, (20km + 1600m ascent).
Coincidentally, at the top of the pass is a Lodge with a bar, the highest pub in Africa, currently busy with tourists on day trips where they essentially just get driven up the hill for lunch.
Still, a log fire, vin chaud and soup are always nice, fortifying me for the descent, during which the rain got worse, turned into snow, and I arrived back at the SA border somewhat damp.
The most interesting part was yet to come though, as the rain had turned the 14km dirt road into a slippery mud bath, which I slowly slid around on, praying I wouldn't fall off the sides of the road into a deep ditch or worse!
Needless to say I survived thanks to my amazing rally driving skills.
