The prominent tourist attraction of the National Park is Doi Inthanon ,which is the highest mountaintop in Thailand. It is an ideal destination for most Thai people to visit at least once in their lifetime. The weather on the mountaintop of Doi Inthanon is freezing. And in winter, Doi Inthanon will be covered with the sea of fog, which is an exclusive atmosphere and cannot be seen in other parts of the country.
There are strange plants growing on the mountaintop of Doi Inthanon due to the atmosphere like primitive forests. Plants are covered with alga and moss. Species of flowering plants such as wild roses are similar to those at Phu Kradueng but they are much larger like 'thousand-year roses'. Moreover, there are fields of green and brown Kaotok Ruesi, a species of moss, which grows only in highland regions with high humidity and cold weather.
