Travel from Bangkok to Thailand's Umphang district, near the border of Myanmar (Burma), for a jungle experience that includes three days of trekking through the tropical forest. You'll go rafting on the Mae Klong River, swim at the bottom of Thi Lo Su waterfall, stay overnight in a Karen hill tribe village, and round up the village elephants with their handlers. You’ll also visit towns like Umphang and Mae Sot, a great way to experience rural Thailand. This small-group guided tour is limited to 10 people and is designed for physically fit people who don’t mind roughing it.
