They cause less impact on the fragile environent and the natural way of life of these rural peoples. In the two longer treks you experience an overnight stay with a hill tribe in their traditional house and camping out in the jungle surrounded by pure beauty. The guides prepare and cook for you. They can also provide for vegetarian or others with special dietary needs. Just say so in advance.
Drinking water is provided the first day.
The following day they boil and purify the water. Do something different from other tourists. Disclaimer I, glen , am not being compensated for creating this web page. This advertisement for the No. 4 Guesthouse and Umphang Trek are posted here simply because I am a friend and fan of Mr. Om and his operation. I lived in Thailand for 8 months, much of it in the jungle, and the most spectacular scenery I saw was on this trek.
