I took a nice hike near Hin Lat Waterfalls very close to my home in Koh Samui.
It was a quiet day and the only other people there were the monks that live there.
To get to the top of the waterfalls I had to climb for about 1K up a very skinny slippery slope in the worst flip flops you can imagine. Needless to say I took it slow.
Once up top, it was very rewarding. The height of the monsoon season has provided a roaring waterfalls. I took off my shoes and sat with my feet in the raging river.
I was too scared to go in more because of the force of the falls was intimidating as you can see from the video.
