Located in Thoeng District, more than 110 kilometers from the city of Chiang Rai, Mount Phu Chi Fah is the most famous in the province. In winter, many Thais go there for its freshness and to watch the sun rise over the morning mist sea. Culminating at 1628 meters above sea level (a sign indicates this), it offers a dominant life on the Loas down the valley. Because it is the other peculiarity of the place, it is pile poile on the border. A terminal also indicates '' Thailand '' on one side and '' Laos '' on the other.
We mostly come to Phu Chi Fah for the view, up there of course, but also on the way. So, check the weather before you go there. I recommend taking the road that goes through Phu Sang Park, it is longer than thirty kilometers but the scenery is more beautiful and then you can make a short stop at the Phu Sang waterfall. Note that there are a lot of resorts and guesthouses up there by very few are present on the booking site.
