Khao Chang Phueak is a high peak located within Thong Pha Phum National Park. Standing approximately 1,249 meters above sea level, it's renowned as one of Thailand's most beautiful and challenging hiking trails. This route is famous for its narrow ridge stretching through the Tenasserim Mountains, which form the border between Thailand and Myanmar. The breathtaking landscape has made Khao Chang Phueak a dream destination for hikers nationwide, especially during the winter months when mist blankets the peak in the mornings, accompanied by cool, comfortable temperatures throughout the day.

The Khao Chang Phueak hiking trail begins near Ban E-Tong and Pilok Mine, a former mining area now a small tourist community nestled in the mountains. From the starting point, hikers will trek through forests and along ridges for approximately 8-9 kilometers. The trail features sections through bamboo forests, evergreen forests, open grasslands, and steep inclines requiring considerable effort. Along the way, stunning views of layered mountain ranges are clearly visible, particularly during the morning and evening when sunlight illuminates the ridges, creating breathtaking landscapes. The most significant highlight is the "Knife Edge Ridge," a narrow, knife-like ridge stretching through a ravine, considered the most thrilling and exhilarating part of the journey. Many tourists consider this area a symbol of conquering Khao Chang Phueak (White Elephant Mountain), as it requires concentration, caution, and confidence for each step.

Although the distance isn't very long compared to other hiking trails in Thailand, the challenge of Khao Chang Phueak lies in its terrain, which includes steep slopes and open ridges. Hikers face sun, strong winds, and fatigue throughout the journey. Thong Pha Phum National Park has implemented strict safety measures, limiting the number of hikers per day and assigning guides or rangers along the route to preserve the natural environment and minimize environmental impact. Therefore, those wishing to hike Khao Chang Phueak must book in advance, as there is high demand each year, and reservations fill up quickly as soon as the season opens.

At the summit of Khao Chang Phueak, hikers will experience a 360-degree panoramic view over the Tenasserim Mountains. They can see the vast, unspoiled forest of the Western Forest Complex, one of Thailand's most important conservation areas. In the mornings, mist often floats over the valleys, while at night the sky is completely dark, making it ideal for stargazing. Because the area is far from city lights, the atmosphere at the summit is peaceful and offers a true connection with nature. Most hikers prefer to camp overnight to watch the sunrise, considered the most beautiful time of the hike.

In addition to its natural beauty Khao Chang Phueak also reflects the importance of ecotourism in Thailand's western forest area. Thong Pha Phum National Park continuously strives to control the number of tourists and maintain the trails to preserve the ecosystem and minimize its impact on nature. Therefore, all tourists should strictly adhere to the park's rules, such as not littering, not making loud noises that disturb wildlife, and avoiding damaging vegetation along the way, so that Khao Chang Phueak can remain a beautiful and pristine hiking trail for future generations.
