Found 2 videos from the net on rains on Kinabalu.
The first video is taken from Gurkha Hut, a remote hut up on the mountain, in which normal Summit Trail climbers will no be able to see it. It’s a small hut for 4, especially for those hard core climbers and like the adventure of mountain camping.
The second one was taken from Sayat-sayat Hut, the last hut before Low’s Peak. The second video looks a bit scary as the mountain trail was flooded heavily. Looks really, really dangerous for us to either climb up or down.
