You can also get some good info on the current weather conditions at Giant's Castle from this news feed:

About the incident with the hikers, I will also get some more info and update the site with it. I'm guessing it happend around the Organ Pipes area and that the smugglers mistook the hikers to be a KZN Wildlife patrol - this kind of thing happened there last year too.
Lukas, its 1-2 hours to drive to Injasuthi from Winterton. The dirt road is not that great but can be driven by regular vehicles without any problems. There have been security problems along this road (but none that I'm aware of in the last 2 years or so), so be aware of potentially being road blocked by cows or people. Kids have also been known to throw stones at cars. Avoid driving in the dark.
Stijn, climb safe. Magan, what caves you heading to?
I envy you guys in the Berg this weekend - hope you have an awesome time! I`m not anywhere near the Berg, but just to make me feel a little better I`ve just spent an awesome 9 days in the Canadian Rockies!
