Rafting in Satun

Hi,

Has anyone been rafting/kayaking in Satun I think its at Tham phu pha pet?) I understand there are just mini rapids but I am struggling to find much more information about it. Where would be the best place to stay? Should I stay in Satun town ? Can I arrange it from there? How far from Satun town is the area you start your rafting from? Any help or advice would be great. I have a day to spare before I head out to Koh Lipe and thought it might be fun. Thank you.
