Khao Krachom, located in Suan Phueng District, Ratchaburi Province, is one of the most famous viewpoints for observing the sea of ​​mist and sunrise in western Thailand. Situated in the Tenasserim Mountains near the Thai-Myanmar border, it sits at an elevation of approximately 1,000–1,045 meters above sea level, resulting in cool temperatures year-round. During the rainy and winter seasons, temperatures at the summit in the early morning can drop below 15 degrees Celsius, making it a popular destination for tourists seeking nature close to Bangkok, just a few hours' drive away.

In the past, Khao Krachom was a tin and tungsten mining concession area. The original mountain roads were used for transporting ore and for local villagers. After the mining operations ceased, the area gradually transformed into a nature and adventure tourism destination. Currently, the road to Khao Krachom remains a dirt and off-road track with steep inclines, many sections with ruts, mud, and narrow paths, making it inaccessible to regular cars. Only 4x4 vehicles can ascend. Many tourists prefer to use the pickup trucks provided by local villagers, which has become a significant source of income for the local community in Suan Phueng District.

The most significant highlight of Khao Krachom is the breathtaking sea of ​​mist in the early morning. Especially after a fresh rain or during the winter, when cold air masses collide with moisture from the mountains and forests, a thick sea of ​​fog forms, covering the valleys below. Tourists often begin their ascent as around 4-5 am to catch the sunrise over the complex mountain ranges. From the summit, you can see the forests of both Thailand and Myanmar in the distance. On clear days, you can see the beautiful layers of mountains stacked on top of each other, earning it recognition as one of the most beautiful fog viewing spots in Ratchaburi province.

The summit is a wide open area that can accommodate many tourists, with several viewpoints for photographing the sea of ​​fog, the sunrise, and the surrounding mountain ranges. In addition, Khao Krajom is popular with stargazers and Milky Way photographers because it is far from the city and has relatively little light pollution. On clear nights, the stars are clearly visible, especially during the late rainy season and early winter, which is a popular season for nature photographers.

Although Khao Krajom has become a more popular natural tourist destination in recent years, the surrounding area still retains the rich ecosystem of the Tenasserim mountain range. Tourists should therefore help maintain cleanliness, not litter, and strictly follow the instructions of officials or locals, especially during the rainy season when the trails may be slippery and the fog may be thick. Warm clothing and hiking shoes are recommended. And rain gear is essential for a trip up Khao Krajom to ensure a safe experience and fully enjoy the natural beauty of Suan Phueng.
