“Pala-U is a 15-level waterfall along a creek stretching out to the Burmese border. It’s about 60 km west of Hua Hin. It’s in the south end of Kaeng Krachan national park (Thailand’s biggest national park).” (1)

 There are some small wild animals can expect along the way such as butterflies, birds, and elephants.
