DOI Inthanon is the highest mountain complex, beautiful and attractive in nature. There is an abundance of wildlife, we watch. DOI Inthanon, also have Thailand National Astronomical Research Institute. Observatory, which is the largest in ASEAN. Minimum temperature during cold usually occur around the area, the amount of grass frost on the DOI, which seems pretty well I wanted it exciting and touching air nao. I would like to watch the sunset, shining light came out beautifully and in the middle of the night, I like watching stars there. And this is why I wanted to go here most.
