Khao Sok is a wonderful rainforest park - we only had a few hours but did a short hike and got drowned in a terrible downpour (I also got a leech on my foot which reminded me of Kai's story of camping around Kanchanaburi!).

Yes, still in my memory. I got 2 leeches from midnight until dawn between the fingers of my foot. They look very fat
