Loei is a little-visited province which is quite unlike any other part of northeastern Thailand. Loei is sparsely populated because of its mountainous geography, which makes it one of the most strikingly scenic provinces in Thailand. For Thais it is worth a visit during the cool season just to feel the novelty of a frost.

The two major national parks in Loei province are Phu Rua and Phu Kradung, both of which contain peaks that rise more than 1,300 metres above sea level. These parks are famous for their wide variety of wild flowers.
