Shuttle was late as per the latest pickup time so i called to local supplier, which was easy communicated with. The operator spoke English and called the driver while i was on line. The guide Danny is a friendly and knowledgeable person. He shared not only the introduction of the tour but also the knowledge of locals. Don't worry to get wet as the bamboo rafting was really fun without danger as the river is shallow during my visit as dry season un February. However, I would highly recommend to wear sandals atleast as you wont be interested to dry them for days. Also, you are suggested to wear swim suit in advance as the fitting room is too local that even Thai will not do it there.
The programme is of good value for what you paid - elephant riding is interesting, raft tour is exciting (make sure you are in suitable clothing and wear slippers because you will be 100 % getting wet). Tribe and waterfall visits were a bit disappointed in terms of the rather low quality of places being visited. After all, it's a nice experience. Do book it through Klook and you will save your money.
