It is only recently that Thi Lo Re Waterfall (น้ำตกทีลอเร) has been promoted. It is a waterfall dropping directly into Klong River deep in Thungyai Naresuan Wildlife Sanctuary with no road access. Only traveling with tour companies is possible. The journey to the waterfall typically involves white water rafting the Klong River of about 40 km through rapids of Class 4 or 5 while the journey back is by walking or riding elephants. The trip takes two to three days. Pre To Lo Su (น้ำตกเปรโต๊ะลอซู) or Pi Tu Kro Lo Su (น้ำตกปี๊ตรุโกรลอซู) is another recently discovered waterfall. It is on Ma Muang Sam Muen (เขามะม่วงสามหมี่น). Two steams fall to combine to become a heart-shaped waterfall. Travel to and from the waterfall requires a few days of hiking. Some other places of interest are Takobi Cave (ถ้ำตะโค๊ะบิ), a cave formerly used by Communist Party of Thailand; Doi Hua Mot (ดอยหัวหมด), a viewpoint above the clouds; and Ban Pa La Ta (บ้านปะละทะ), a Karen village dating back 250 years.
