Greet the first sunrise of Thailand at Pha Chana Dai, Dong Na Tham Forest. It is located to the north of Pha Taem National Park - the easternmost point of the country along the Mekong River and the first place in the kingdom to be bathed by the first rays of sunrise. At dawn, a sea of mists floats over the riparian side of the Mekong River. The forest allows tourists to enjoy the nature, flora, mountain and the Mekong River. From September to November is the best time to enjoy the nature around while flowers are in full bloom, as well as waterfalls and fogs over the Mekong River. From January to March is the best time to see the forest change its hue, with trees shedding their leaves, and to cruise in the Mekong from Ban Pak La to Khan Tha Kwian.
