Doi Inthanon mountain complex is beautiful, fascinating natural wildlife and has a lot to us. Another major difference with the Doi Inthanon National Astronomical Research Institute of Thailand, which is also the observatory is the largest in ASEAN. At the lowest temperature or cold frost usually occurs. Top general area of grass on the hill. Which is pretty good, it's exciting and I want to experience cold weather. I want the sun to shine out beautifully, and at night I would lie there watching the stars. And this is why I want to go here most I like the mountains. I like and I like wild natural state. It's a beautiful thing for myself and many people experience it, then you'll love Thailand Tourism Thailand.
