• Namtok Khun Phawo (น้ำตกขุนพะวอ) A large waterfall around 100 m high and an origin of Huai Mae Charao (Mae Charao Creek).
• Huai Mae Lamao (ห้วยแม่ละเมา) This large creek is in an unspoiled forest, offering whitewater rafting on rubber dinghies.
• Nature Trail (เส้นทางเดินศึกษาธรรมชาติ) The walking path goes up and down the fairly steep hills, and passes along the river upstream and a small waterfall. During the period of change from the rainy to cool season, colourful wild flowers can be seen. The greenery is dotted with strikingly red Krathue (Boesenbergia prainiana) and yellow Mexican sunflowers.
• Namtok Pha Thewa (น้ำตกผาเทวะ) It is on the nature trail and the most remarkable waterfall of the park. With a height of 150 m, the powerful flow falls against boulders and the pool below. In the woods, there is a pagoda containing cremated bones of a heartbroken woman who hung herself.
• Tham Mae Usu (ถ้ำแม่อุสุ) This cave is around 12 km from the Tha Song Yang District Office to the north. To the west, there is a gigantic hollow rock. In the afternoon, rays of sunlight illuminate the cave.
