Pha Dong Kor is a cliff with an elevation of approximately 622 meters above sea level, located within Phu Pha Lek National Park. This national park spans several provinces, including Sakon Nakhon, Udon Thani, and Kalasin. As the highest point of the Phu Phan mountain range, Pha Dong Kor is a prime spot for taking in the scenic views and capturing amazing photographs.

Beyond Pha Dong Kor, the national park offers other interesting attractions, such as Pha Suriyan, a spot for watching the sunrise, and Lan Usasawan, a field known for its beautiful wild flowers. There is also the Haw Song Dao viewpoint, perfect for stargazing, and ancient historical sites like the prehistoric cave paintings at Pha Phak Wan and dinosaur fossils in certain areas.

The park also provides camping facilities for visitors who want to spend the night and immerse themselves in nature.

• Travel by car from the city of Sakon Nakhon or nearby provinces.

• Drive along Highway 22 (Sakon Nakhon-Udon Thani) until you reach the 95 km marker, then turn right.

• Take the Rural Road (Ror Por Chor) from Ban Tai-Don Som Hong until the intersection for Ban Phon Sawang, then turn right onto the Rural Road from Ban Phon Sawang-Phu Pha Lek for about 6 more kilometers until you reach the park headquarters.

• From the headquarters, you can drive to various spots like Haw Song Dao and Pha Dong Kor.

• During the rainy season, the park is lush and green, but you should bring rain gear and appropriate footwear.

• In the winter, the forest's colors change, and the cool weather is perfect for camping.

• It's always a good idea to check the operating hours and any specific regulations with the park officials before your visit.
