How scary and challenging is the Via Ferrata on Mt Kinabalu for someone with a moderate fear of heights?
Well, while it look like fun (http://www.flickr.com/photos/eriani69/sets/72157625599824027/) and is probably well run and well protected, don't underestimate this mountain.
I've been up there and it was seriously cold. We actually turned around before reaching the summit because of fears over hypothermia, and if you think I'm kidding, it killed a couple of SAS soldiers some years ago.
Just because it's on the equator doesn't mean it isn't a mountain.
So if you go, just be a little bit prepared. about 8 years ago
