Also within the park's boundaries is the formidable Khao Mokoju mountain, which soars to 1,964 metres and requires a five-day trek to the summit. A more manageable viewpoint is Chong Yen, reputed to be an outstanding sunset perch located 28 km from park headquarters along the only road. Along the way you might catch a glimpse of wild jackal, porcupine, 450 bird species and rare flowers that grow in the high altitudes.
