Khao Kho is a small district in the northern area of Phetchabun province in Thailand with beautiful mountains and flat plains. The highest peak at 5,801 feet is at Phu Tub Berg, also known as the Sea of Mist due to the fog which forms over the mountains. The views and temperature at this altitude are some of the most amazing moments to explore and experience. It can be as low as 12c at night. By waking up early, you are sure enough to take the most beautiful sunrise over the mountains.
