In my last trip in Langkawi I had a crazy encounter with few monkeys. They were clearly used to the tourists, and the feeding that comes with it of course. They were absolutely fearless, they did not hesitate a single second to jump on the approaching boats. I was really surprised by this mum that took even the little kid with her.
